Voting for the two positions left vacant by the resignation of Barry de Jong and Ian Cope will take place by postal election, held by the WA Electoral Commissioner.
Until now, the Town has held in-person elections with the chief executive officer acting as returning officer.
In a report to council, chief executive Stuart Wearne said the cost of a postal vote would be in the region of $15,000 compared to $5000 for a council run election.
There could be a higher turn out for a postal election, however and there would be less administrative pressure to conduct it.
But despite the additional workload, Mr Wearne said in his report that he had always supported the town holding its own in person elections.
The election is expected to be held in June.
