Australia’s budget airlines. But on weekends he still gets a buzz talking to groups of kids and adults and putting on a short display of aerobatics at the RAAF Air Force base at Point Cook, just outside of Melbourne – the longest continuous operational Air Force base anywhere in the world.
The plane being put through its paces today was a Mustang, built at Fisherman’s Bend in Australia in the 1950’s as the only place outside of the USA licensed for production. With a huge 12 cylinder Merlin engine, this plane had speed and endurance and as it completed loops and high speed rolls above us as a dad I couldn’t help wish that I had learnt how to fly as a kid. As Darcy returned to the ground in the Mustang my 7 year old daughter asked “Dad, when can I learn to fly”

I imagine amongst the group there to watch the display this weekend, it was a common thought for kids and adults alike.
The air displays are a regular (and clearly popular) attraction at Point Cook with displays at 1pm each Tuesday, Thursday and Sundaythroughout the year with regular aircraft featured including the Winjeel, Harvard, CT4A, Sopwith Pup replica, Tiger Moth and Mustang. In addition visiting aircraft such as the DC3, Bird Dog or even a modern PC-9 can sometimes be seen.

If you want to extend your day the point cook area just next to the Air Force base is the Point Cook Coastal Park, with walking trails and great views across Port Phillip Bay back to Melbourne as well as a wetland area teeming with bird life. Not far away is Weribee park and the open plains zoo.
