Punting 101: Line Betting

What Is Line Betting?

Line betting is a form of betting where the market is handicapped to make both betting outcomes equal. The bookmakers achieve this by giving both teams a margin, known as a line. If the bookmakers believe that one side is 12.5 points better than their opposition, you can back them to win by 13 or more points. Alternatively, you can back their opposition to either win the match or lose by less than 13 points. This gives you the chance to back a team at healthy odds, no matter how short or long they are on the Head to Head (H2H) market.

The example below shows the market for a game of AFL between GWS and Port Adelaide. GWS are the heavy favourites on the H2H market, paying $1.30 to win. The bookmakers have declared that in order for the odds to be even, GWS need to start 24.5 points behind their opposition, or Port Adelaide need a head start of 24.5 points.


Team H2H Odds Line Line Odds
Greater Western Sydney $1.30 -24.5 $1.91
Port Adelaide $3.50 +24.5 $1.91

How Do I Know If My Line Bet Is a Winner?

Working out the result of a line bet is relatively simple – just add or subtract the line from your team’s score and if their score is higher than their oppositions, it’s a winning bet.

For example, if you backed GWS at the line of -24.5, and GWS ended up winning 102-90, your bet would be unsuccessful because their adjusted total is less than Port Adelaide’s score of 90. Alternatively, if you backed GWS at the line of -24.5 and GWS ended up winning 150-90, your bet would be successful because their adjusted total is greater than Port Adelaide’s score of 90.
