Improvement works to the second hole at Glen Waverley Golf Course will begin on 18 January.
The improvements include works to reshape and drain the bunker so the green can be played on all year round.
Couch grass will also be laid on the area surrounding the green.
Two trees behind the tee will be removed to extend the tee by eight metres, to allow for more tee off area and to lengthen the hole.
The works are expected to take around 10 weeks.
A temporary second hole and tee off will be set up for golfers to use while the works are taking place.
