Best lay bets in Australia for Friday, May 31 brought to you by expert form analysts from the Betfair Hub.

Lay bets are an offering unique to Betfair in Australia where punters can bet AGAINST a particular outcome.

THOROUGHBREDS

Port Augusta: Race 6; #4 Fair Legacy 

Won with a leg in the air at this track/dist last start by 6L at $1.28. Beat absolutely nothing that day. Goes up 3kg in weight and 1498m time was much slower than key rivals ran in a different race over this trip.

GREYHOUNDS

Ballarat: Race 1; #6 Temper Tantrum 

Temper Tantrum had every chance at Warrnambool last start and seemed to go backwards based on her good effort the start before which was at this venue. Even if she improves here back at Ballarat this race has some depth and I could see her getting swamped late.

Ballarat: Race 2; #2 Extreme Avenger 

Extreme Avenger may face a lot more pressure then she did in her Maiden Heat last week and I can see her getting shuffled back in the early stages and that should be enough to get her beaten.

HARNESS

Mildura: Race 6; #1 Letsgo Matilda 

Most punters will have Letsgo Matlida leading from its pole draw so will likely be popular and short fav. The fact is its drawn barrier 1 on four occasions and never led. Based on that likely be to a risk early in the contest and worth taking on.
