The full fire power of Flagstaff Hill in Warrnambool will be on show this weekend.
For the first time since 2015, both cannons will fire on Easter Sunday.
The cannons, which are 80 pound Rifle Muzzle Loader guns, will be fired at 2.30pm.
Flagstaff Hill is the only place in the Southern Hemisphere that has two of these guns on location.
Flagstaff Hill will be a hive of activity this weekend, with other activities including an Easter Bunny Trail scavenger hunt on Easter Saturday.
