The State Government will allow people to recreationally fish without a licence on Sunday.
Normally, licences are required at this time of year for catching rock lobsters and recreational fishing from a powered boat.
The licence-free day is in celebration of National Gone Fishing Day, held on October 20.
While people will be permitted to fish without a licence, all other rules will still be in effect, including fish-size limits and area closures.
WA Fisheries Minister Dave Kelly described fishing as an experience with social and economic value, as well as providing health and relaxation benefits.
