The state government has approved two Shark Monitoring Network receivers and an alert tower at Bunker Bay after the shark attack in late July.
Dunsborough surfer Phil Mummert was bitten and knocked off his surfboard by a white shark on July 31.
Fisheries minister Peter Tinley said the most recent incident was not fatal but the popular beach did see the tragic death of 21-year-old Kyle Burden in 2011.
The two new receivers, which are scheduled for installed in October, can detect tagged sharks up to 400 metres away and aim to provide the best coverage option for Bunker Bay.
Once on line, the receivers will expand Western Australia's Shark Monitoring Network to 34 locations - nine of which have been added by the McGowan Government, including four along the Esperance coast and three near Gracetown.
As with Esperance and the coastal zone for the SMART Drumline Trial, a shark warning system will be installed on a beach site, between the two new Bunker Bay receivers.
"The McGowan Government supports a wide range of initiatives to keep beach-goers informed on shark activity via the SharkSmart WA App and website and Surf Life Saving's Twitter service," Mr Tinley said.
"We are doing more than ever to keep you safe at the beach and as the weather warms up over spring, we remind everyone to switch on their Sea Sense and take good care. You can find out more on the Sharksmart WA app or the Sharksmart website."
The City of Busselton will operate the tower's lights and sirens, which can be activated to alert water users when a tagged shark is detected or if there is a reported shark sighting.
Mr Tinley said he appreciated the City of Busselton taking on the job of locating the Shark Warning System and the ongoing operations of the tower.
"The chance of shark encounter in WA is low, but we want all water users to stay safe," he said.
The estimated cost of the two new receivers is $150,000 while the alert tower will cost $15,000 to install.
