Lay bets are an offering unique to Betfair in Australia where punters can bet AGAINST a particular outcome.
THOROUGHBREDS
I am happy to be against Timbolton at the current price. Comes into this with a 39 day gap between runs. Gets an apprentice jockey after having a senior jockey riding the last couple of starts and will need to overcome the widest gate to win.
Newcastle: Race 7; #5 Miss Lenorr 
Yet to win when first up and with an apprentice taking the ride I am happy to risk at the current price. Last prep she took a few starts to start performing and she likely needs further than the 1200m distance on offer today.
HARNESS
Albion Park: Race 4; #1 Crime Time
Crime Time was just plain last time out beaten 11m in 1.57.4 over the mile. He jumps out of three consecutive NR30-40 grade races into a hot NR 41 to 47 over the middle trip.
Gloucester Park: Race 1; #6 Hotly Pursued
Think this bloke is worth taking on given the fact he has drawn outside Runningonempty and will be doing the work first up. He is a nice horse but just too short from the draw first up.
