Metre posts, Sandbelt bunkers and the Slope Rating: reading an Australian course map

Most of us look at a course map the way we look at a train map in a city we are visiting: long enough to find the next stop, never long enough to understand the network. The diagram on the scorecard, the sign on the tee, the metre post beside the fairway, the planner in the pro shop all carry more than a picture of the hole. Read properly, they tell you where the hole wants you to miss.

A map will not fix your swing. It stops you aiming a decent swing at the one spot where it costs a shot, and for a golfer who shoots in the 90s that is worth more than anything you could change on the range this month. With spring here and the southern season about to start, it is a good habit to take into your first comps.

What a course map is actually telling you

There are four kinds of map on an Australian course, and they do not say the same thing. The scorecard diagram is a sketch, rarely drawn to scale. The tee sign is often the same sketch, bigger, with the metres from each set of tees. A proper course guide is drawn from a survey, to scale, with distances to carry bunkers and reach water. A GPS screen, on a cart or in an app, sits on satellite imagery and measures from where you stand.

Before you trust any number, ask two questions. First, measured from where? Tee signs count from a fixed plate or marker, and the tee blocks may have been moved several metres forward or back that morning. Second, measured to where? Many Australian clubs measure fairway distances to the centre of the green, but not all of them: some measure sprinkler heads to the front. The local rules usually say which, in small print, and it is the most expensive line on the card to skip.

Five things to find on every hole before you tee off

• Your landing zone. Take your real carry with the club you plan to hit, not your best drive of the year, and find that distance on the hole. What is there: fairway, a bunker, the edge of a penalty area, a dogleg you will run straight through?
• The width at that distance. Holes narrow and widen. The fairway might be 40 metres wide at 180 and 25 metres wide at 230. That is often the best argument for a shorter club off the tee.
• The lines that cost shots. White stakes or lines mark out of bounds, which is stroke and distance. Red and yellow mark penalty areas, where you drop with a one stroke penalty. A map that shows OB tight on one side and a penalty area on the other has just told you which way to favour.
• The green’s depth and shape. A green 30 metres deep is a two or three club green depending on the flag. A kidney shaped green with a bunker in the gap is really two small targets.
• The short side. Look at where the trouble sits around the green. Missing on the side with no bunker and plenty of green to work with is a bogey at worst. Missing on the other side is how doubles happen.

Reading the numbers: carry, reach, front, back

A good course guide gives two numbers for a hazard, and mixing them up is the most common way golfers find the bunker they were trying to clear. The number to reach a bunker is the distance to its front edge. The number to carry it is the distance to its back edge. On a fairway bunker those can be 20 metres apart. If your drive carries 200 and the bunker is 190 to reach and 210 to carry, you are hitting straight into it.

Greens work the same way. A hole that plays 140 to the centre might be 127 to the front and 153 to the back. A front flag makes the centre number a club too long, a back flag a club too short. Some clubs put out a daily pin sheet or use coloured flags to show roughly where the hole is cut; ask in the pro shop.

Plan the hole backward from the green

The habit that turns a map into shots saved is simple: decide where you want to hit your approach from, then work back to the tee.

Take a 360 metre par 4. The map shows a fairway bunker on the left, 210 to reach and 235 to carry, and a penalty area down the right from 215 to 255. The green is 27 metres deep with a bunker short left. Driver looks like the natural club. It is also the club that brings both hazards into play.

Now work backward. Your most reliable full approach is a 9 iron at about 125 metres. From 125 out, the tee shot needs to travel 235 metres, which is exactly where both hazards pinch. A hybrid at 185 leaves 175, a long approach, but from the widest part of the fairway. A 3 wood at 205 leaves 155 with a 6 iron, from short of both hazards. The map has turned a hopeful driver into a choice between two sensible clubs, and it has told you to aim the approach at the right half of the green, away from the bunker short left.

Make the map your own

Printed maps are written for everyone. If you play the same course most weekends, print the hole diagrams and mark them up at home: your carry for driver, 3 wood and hybrid on each tee, a circle where a miss costs a shot, an arrow to the safe side, and after each round a dot where your tee shots actually finished. Three rounds in, the dots tell you which way you really miss.

The Rules allow all of this. Handwritten notes are fine, as long as you are not building a detailed replica of the green contours. Since 1 January 2019, the USGA and The R&A have limited images of putting greens used during a round to a scale of 1:480, or roughly 1 cm to 4.8 m, or smaller. A rangefinder or GPS is allowed too, unless the committee has adopted the Local Rule that bans them (Model Local Rule G-5), but the function that measures elevation must be off. The first breach costs the general penalty, and a second one in the same round means disqualification.

Where Australian golfers find the numbers they can trust

Start beside the fairway. Australian courses measure in metres and most mark key distances with posts or discs, but the colour code is not national. At The Coast Golf Club in Sydney the local rules list blue posts at 200 metres, white at 150 and red at 100, all to the centre of the green. At Seabrook Golf Club the markers are white at 100 metres and blue at 150, also to the centre. Change clubs and white can mean 100 or 150, a two club difference. Sprinkler heads often carry a number too, and not always to the same point: at Spring Valley Golf Club they measure to the front of the green. So before the first tee, read the local rules or ask at the counter: what do the colours mean, and centre or front?

Then turn the scorecard over. Next to par and the metres from each set of tees you will find the Scratch Rating, how hard those tees play for a scratch golfer, and the Slope Rating, how much harder they play for a bogey golfer. With par, they turn your GA Handicap into your Daily Handicap for that course and those tees, and many clubs put up Daily Handicap look-up charts so you can find your number in seconds. If you still call it your GolfLink handicap: that system was shut down in late September 2025 and replaced on 2 October 2025 by Golf Australia CONNECT, with your handicap now in the Golf Australia Official App and your old GolfLink number kept as your Golf ID.

The back of the card is where the local rules live, and on an Australian course that often means native vegetation. Clubs can protect bushland as a no play zone, often marked with red stakes with green tops: a penalty area you may not play from. The Coast Golf Club uses exactly that marking beside its 17th. On the map, treat scrub marked this way as water: however playable the lie looks, you are taking a drop and a penalty.

On the Melbourne Sandbelt the map needs one more layer. Royal Melbourne describes the bunkering on its West Course as crisp, with vertical edges that chew into fairways and putting surfaces, and across the Sandbelt bunkers sit tight to the greens. There is often little room between a miss and the sand, so the short side of a Sandbelt green is usually a bunker shot, not a chip. Firm, sandy ground also adds run-out the map cannot show, so plan to land the ball short of the centre number.

For the maps themselves, some clubs publish a hole by hole guide on their website; playing somewhere new, print it the night before and do the backward planning on the kitchen bench. If your cart has a GPS screen or you use a phone app, ask one question of it: does it know today’s flag, or only the middle of the green? At a council course with nothing but a tee sign, the habit still works: find the nearest metre post, check what its colour means, and find the short side.

A thirty second routine for every tee

• Check the tee you are on, what the marker colours mean, and whether the numbers are to the centre or the front.
• Find your real carry on the map and look at what sits there, and how wide the hole is.
• Locate out of bounds, the penalty areas and any green-topped no play zones, and decide which side to favour.
• Pick your ideal approach distance and choose the tee club that leaves it.
• Note the short side of the green before you get there, and on sandy courses assume it is a bunker.
