Yes it was agreat movie and there was a new one made a few years ago too but I haven't seen it.
As for my home town at 4000 people- it is actually one of the larger towns around there too. Although Merimbula, one town next to it on the coast was only 3500 when I left in 1987, but has now grown to 14000 (35 yrs later) as it is such a gorgeous town and many older people have moved there to retire away from the cities.

And the rest are still villages. And yes, knowing everyone is not so much fun and I'm a city girl at heart, which is why I love Melbourne so much.
I hope that you enjoy #StormBoy
