Spiderman, Monash's Nursing School has been in Frankston for almost two decades, if not longer. A good chunk of the enrolment are postgrads from overseas.
For my spouse and I, the attraction for Frankston did not lie in it being a beachside suburb. For us, it was because most of the houses (thanks Granddad) are on subdivisible blocks. The other attraction was the local high school. The presence of plenty of infrastructure was also a bonus.
If it wasn't a beachside suburb you probably wouldn't have bought there though
And if frankston was 15 km inland and didn't attract people with aspirations then the high school would still be crap
Cranbourne?
I'd take frankston because it's on the beach and has a much better chance of being considered a desirable location by future ppor buyers
The beach is a proven investment strategy
