Western Australia's police minister has admitted fining a Perth dad for drinking a beer while fishing seems excessive.

Doug Vickery copped a $200 fine at Two Rocks Marina last week, a decision that has now been referred to the Police Commissioner.

“At first glance it seems like a pretty interesting case because I’m sure he's not the only person who’s fishing off the beach or rocks that’s had a beer,” WA Police Minister Michelle Roberts said.

The 36-year-old electrician has accused police of being "un-Australian" and "revenue raising".

The state government has now asked the force for a “please explain”.

“It’s not something I can interfere in, it’s something I’ll ask the commissioner about and it'll be his call whether he wants to review it or not,” Ms Roberts said.

Officers told 9NEWS they spoke to the fisherman within an hour of receiving calls about someone speeding in the area, meeting their target response time.

Today police said they have no further comment to make about the matter.

Last week police fined a motorcyclist $550 for loosening the chin strap on his helmet.

In both cases, the fines are at the discretion of the individual officer.

Mr Vickery still hopes his fine will be reviewed.
