Ruthless finishing saw Rob Gerrard collect another brace, along with Joe McCormack after a pre-match 5km warm-up run.

Further goals came from Wes Chugg, Jesse Fulton, Tom Burk and an own goal.

Riverside joined Devonport on 19 points after picking up their fifth win in six games with a 2-0 defeat of Launceston City.

Mitch Roberts curled in a free-kick soon after the break before Josh Taylor resumed tap-in responsibilities with a close-range second.

Launceston United recorded a fourth straight win to stay in contention, returning from Burnie with a 3-0 success.

Yasin Mohammadi bagged a first-half double and when veteran Chris Pickering's body finally started to show its age, Aidan Rigby came off the bench to complete the scoring.

"Always good to get a win at Burnie," said coach Glenn Reading.

"It was a hard-fought physical game and the boys played well and deserved the win."
