Perfect location to build dream home?

Was browsing domain.com.au for real estates in Perth, happened to come across this location, couldn't be closer to perfect I guess?

Ideally located in a quiet suburb with a sea view (Indian Ocean) and within walking distance to the beach, modestly far from city (20km around?), with majority of population around the suburb made up British migrants (more class hor?) and within short driving to Joondalup golf course (where mom and dad used to stayed for 4 days as their retreat) and off course near to Joondalup train station (I can directly hop on the train and head down south to Cannington train station and take a bus to aunt's place.

The vacant land is also modestly spacious at around 7900sqr ft (double my current home size and in Aus, that kind of space is considered modest in Perth!) and the neighborhood isn't considered crowded at all, given its moderately far away from city.

Ah....perfect land to build my cozy town house in Australia, but problem is...where am I going to get the money for it? The piece of land sells for AUD$420k or around RM1.2m, by the time I can afford it, it could be long gone.Let me start finding money when I go KL....and hope that maybe in 10 years time there are still such land available there. :) Oh and by the way, this suburb is called Currambine.
