Scratch Rating, Slope and the 0.93: how your GA Handicap becomes a Daily Handicap in Australia

Spring comps are filling the timesheet again, and the first thing most of us do on arrival is find our name on the Daily Handicap poster near the pro shop, see a number a couple of shots different from our GA Handicap and shrug. That gap is not a mistake and it is not the club being stingy. It comes from two figures printed beside every set of tees in Australia, the Scratch Rating and the Slope Rating, plus a little Australian twist that golfers elsewhere do not have. Once you know what goes into those numbers, you can pick tees with more confidence, understand why a good round on a tough track did more for your handicap than a lower score at home, and stop arguing with the poster.

Scratch Rating is the Australian name for Course Rating

Golfers who read overseas coverage will see the term Course Rating. In Australia, Golf Australia calls the same thing the Scratch Rating, and it has carried that name through the switch to the World Handicap System. It is the number of strokes a golfer with a GA Handicap of 0.0 is expected to need from a given set of tees in normal playing conditions.

One local detail catches people out. Golf Australia’s January 2026 reference guide for administrators says Scratch Ratings here are expressed to the nearest whole number, with .5 rounding up. So where an American card might show 71.6, an Australian card shows 72. Nine-hole Scratch Ratings move in steps of half a stroke.

The Slope Rating is the second figure. It runs from 55 to 155, and 113 is the neutral value for a course of standard relative difficulty. Where the Scratch Rating only cares about the elite player, the slope tells you how quickly the course gets harder as your handicap climbs. Golf Australia puts it neatly in its own example: a high marker might play off 28 on a hard course and 24 on an easier one, while a low marker moves from 4 to 3.

The two imaginary golfers behind the numbers

Both ratings are built on the Course Rating System used around the world, which describes two reference players. Converted to metres, they look like this:

• Scratch man: drives roughly 229 metres and can reach a hole of about 430 metres in two. Scratch woman: drives about 192 metres and reaches about 366 metres in two.
• Bogey man: drives around 183 metres and reaches about 338 metres in two. Bogey woman: drives about 137 metres and reaches about 256 metres in two.

Raters estimate what each of them would score. The scratch player’s estimate becomes the Scratch Rating. The bogey player’s estimate becomes the Bogey Rating, which you will almost never see on a card but which drives the slope.

If you hit your driver about 190 metres on a calm day, you are much closer to the bogey reference than the scratch one, and the slope matters more to you than the Scratch Rating does.

Turning the gap into a slope figure

The slope comes from the difference between the two expected scores. For men, take the Bogey Rating, subtract the Scratch Rating and multiply by 5.381. For women, the multiplier is 4.240.

Picture a men’s set of tees with a Scratch Rating of 72 and a Bogey Rating of 96.8. The gap is 24.8 strokes, and 24.8 × 5.381 = 133.4, so the slope is 133. Now a women’s set with a Scratch Rating of 74 and a Bogey Rating of 101.6: the gap is 27.6, and 27.6 × 4.240 = 117.0, a slope of 117. Both examples are made up for illustration.

What widens that gap is anything that punishes the shorter, less accurate player more than the elite one. Think of a sandbelt-style layout with bunkers eating into the edge of every green, a coastal course where the prevailing wind turns a 140-metre carry over scrub into a lottery, or a bush course where a drive that drifts 20 metres into the trees is gone. A flat, wide-open parkland course can be long and still have a modest slope, because a miss rarely costs more than a shot.

What the raters measure on the ground

The reference guide lists what goes into every rating. First comes effective playing length: the measured distance of each hole, adjusted for roll, wind, elevation changes, altitude, doglegs and forced lay-ups. Firm summer fairways that add run, or a hole that climbs into the prevailing breeze, both shift that figure.

Then there are ten obstacle factors, assessed hole by hole for both reference golfers: topography, fairway, green target, recoverability and rough, bunkers, crossing obstacles, lateral obstacles, trees, green surface and psychology. The last one is the stack effect, where a hole looks fine on paper but asks for a carry over water to a shallow green with a bunker behind it. Each set of tees is rated separately, and men and women receive separate ratings from the same tees.

From GA Handicap to Daily Handicap, the Australian way

Your GA Handicap is the portable number, the equivalent of what the rest of the world calls a Handicap Index. On the day it becomes a Daily Handicap, Australia’s name for the Course Handicap. The standard World Handicap System formula is GA Handicap × (Slope Rating ÷ 113) + (Scratch Rating − Par). Golf Australia then goes one step further.

Since the move to Golf Australia CONNECT in October 2025, the published 18-hole formula is:

Daily Handicap = ((GA Handicap × Slope Rating ÷ 113) + (Scratch Rating − Par)) × 0.93 × Consistency Factor

The 0.93 is what Golf Australia calls the Multiplier, its standard handicap allowance, designed to stop high markers holding an edge over more consistent low markers. Before CONNECT it was applied inside the GA Handicap; now it sits in the Daily Handicap, so GA Handicaps rose slightly at the changeover while the strokes people actually receive stayed broadly the same. Overseas, the usual allowance for individual stroke play is 95 per cent of the Course Handicap; in Australia the 0.93 already does that job. The Consistency Factor is newer still: 0.9986 for men and boys, 1.0483 for women and girls.

Here is how it plays out for a man with a GA Handicap of 16.4, all on par-72 tees:

• Neutral tees, Scratch Rating 72, Slope 113: 16.4 × 113 ÷ 113 = 16.4, plus 0, × 0.93 × 0.9986 = 15.23, so a Daily Handicap of 15. That is why the poster often shows a figure below your GA Handicap.
• Medium tees, Scratch Rating 71, Slope 128: 16.4 × 128 ÷ 113 = 18.58, minus 1 = 17.58, × 0.93 × 0.9986 = 16.32, which rounds to 16.
• Back tees, Scratch Rating 74, Slope 141: 16.4 × 141 ÷ 113 = 20.46, plus 2 = 22.46, × 0.93 × 0.9986 = 20.86, which rounds to 21.

Same golfer, same week, six strokes of difference depending on the tee markers. For a woman with a GA Handicap of 24.0 on tees rated 76 / 132 with a par of 73, the sum is 24.0 × 132 ÷ 113 = 28.04, plus 3 = 31.04, × 0.93 × 1.0483 = 30.26, a Daily Handicap of 30. Results round to the nearest whole number, with .5 going up. Team formats such as four-ball, foursomes and Ambrose use their own allowances on top.

How your round flows back into your handicap

After the round the ratings work in reverse. Each score becomes a Gross Differential, and here Australia again has its own flavour. Because close to four in five handicap rounds in this country are Stableford or par events, Golf Australia converts every score to Stableford before it counts. The 18-hole formula from the reference guide is:

Gross Differential = ((36 − Stableford points) + Daily Handicap + Par − (Scratch Rating + PCC)) × (113 ÷ Slope Rating)

The Stableford conversion does the job that net double bogey does in the rest of the world: once a hole scores zero points, extra strokes no longer hurt your handicap. PCC, the Playing Conditions Calculation, appears in the Golf Australia app as Daily Difficulty. It ranges from −1 to +3 and is worked out automatically from the field’s scores when conditions were well outside normal, say a blustery spring afternoon or a course left soggy by heavy rain.

Your GA Handicap is then the average of your best 8 Gross Differentials from your last 20 rounds. Two examples, again illustrative:

• 33 points at home, Daily Handicap 16, par 72, Scratch Rating 71, slope 128, Daily Difficulty 0: (3 + 16 + 72 − 71) × 113 ÷ 128 = 17.66, a differential of 17.7.
• 38 points on a tougher course, Daily Handicap 21, par 72, Scratch Rating 74, slope 141, Daily Difficulty +1: (−2 + 21 + 72 − 75) × 113 ÷ 141 = 12.82, a differential of 12.8.

Where to find Scratch and Slope Ratings in Australia

The quickest place is the Golf Australia Official App, which replaced the old GOLF Link app and website when Golf Australia CONNECT went live on 2 October 2025. Your GOLF Link number carried over as your Golf ID. The app’s Daily Handicap calculator lets you choose a course and tees and shows your Daily Handicap, and your handicap record there and on golf.com.au lists every Gross Differential and the Daily Difficulty applied to each round.

On site, Golf Australia supplies every club with Daily Handicap look-up posters, one column per set of tees, and its rules require the Scratch Rating, Slope Rating and par of each set of tees to be readily available to players. The scorecard is the other obvious source, though an old card may lag behind a rerating.

As for who sets the numbers: the reference guide says every set of tees is rated by State Association or Golf Australia experts, and an Authorised Association issues the ratings for the courses in its area. In practice that means bodies such as Golf NSW and Golf Victoria. Golf NSW also explains that Golf Australia engaged a statistician to build a process that checks the accuracy of existing ratings against the scores actually posted, so a course that consistently plays harder or easier than its numbers can be flagged for review. Clubs that move tees significantly or rebuild holes are expected to tell their association so the ratings can be revised.

You do not need to belong to a bricks-and-mortar club to have a GA Handicap and see your Daily Handicap for any course. Golf Australia runs its own Golf Australia Club, which in October 2026 listed a subscription at A$15 a month or A$124 a year, covering an official GA Handicap, full app access and personal liability insurance. If you are a club member instead, part of your fees already goes to Golf Australia: Golf North Queensland’s 2026 fee notice lists the Golf Australia affiliation fee at A$32.27 per adult or junior member with a GA Handicap.

Reading the tee sheet like a local

• Compare the Scratch Rating with par. A par-72 course rated 75 from the tips is telling you that even elite golfers expect to go over par.
• Treat the slope as a penalty forecast. If your misses tend to finish in scrub, trees or sand, a slope in the high 130s will cost you more than the extra 300 metres of length suggests.
• Check how much moving forward saves. Stepping up a set of tees often drops the Scratch Rating by two and the slope by six or more. For many mid markers that is the difference between a battle and an enjoyable morning.
• Remember the women’s ratings are separate. From the same tees they are usually higher than the men’s, because every hole is long relative to the women’s reference players.

A quick check before your next comp

• Open the Golf Australia app, pick the course and tees, and note the Scratch Rating, Slope Rating and your Daily Handicap.
• Glance at the Daily Handicap poster at the club to confirm the tees for the day.
• Set a target: 36 points means you played to your handicap, whatever the course.
• If the slope is above 135 and your driver has been wayward, consider the next tees forward for social rounds.
• Afterwards, check the Daily Difficulty on your record and see how your Gross Differential compares with your best eight.

None of this will hole a putt for you, but it explains why 32 points at a sandbelt course in a spring northerly can be a better day than 37 points at home, and why the handicap system rewards it.

How this page was put together: the Scratch Rating, Slope Rating, Daily Handicap, Multiplier, Consistency Factor, Gross Differential and Daily Difficulty rules come from Golf Australia’s WHS reference guide for Australian administrators (January 2026 edition); the scratch and bogey golfer definitions and the slope formula come from the Course Rating System, with distances converted to metres; the Golf Australia Club prices and the 2026 affiliation fee were read in October 2026 on golf.com.au and in Golf North Queensland’s published fee notice.
