Mick Fanning will not begin the defence of his Rip Curl Pro title at Bells Beach until Good Friday.
Organisers decided not to begin the men's event on Thursday, with much bigger waves expected over the Easter long weekend.
The opening round of the women's Rip Curl Pro could get underway on Thursday afternoon, with a decision to be made at 1500 (AEDT).
Three-time world champ Fanning will take a sabbatical from the pro tour once the Bells Beach event is over.
He decided he needed a break following a tough 2015, which included the infamous shark attack in South Africa, a marriage breakup and the death of his brother.
