Shane had the opportunity to tour the factory with Michael Jennings and see firsthand the passion and craftsmanship driving Australian marine manufacturing.

A highlight of the visit was the Australian‑Made Vortum range of silent marine generators — impressive tech, built in‑house and well worth a look for those seeking quality and reliability: www.vortum.com
