I'm not aussie, but I lived in Perth for 2.5 yrs & now living in Singapore for 1.5 yrs. In my point of view, there are several major differences:
1. The pace of life
Generally Spore has a faster pace & very competitive compare to Perth
People here almost always rushing all the time, specially taxi driver.... as I take cab almost everyday...
2. Housing
Living in a shoe box which called
condo is far diffrent with house, specially if you mention yours is big. Children can't run/ jump at home otherwise your neighbour downstair will make noise about it (like mine...
3. Transport
Most people in Perth has a car as it is very affordable, while that's not the case in Spore. Car is very expensive, so do the running cost of it. Most people take public transport, good & affordable but taxi not always easy, ie taking taxi in certain time of the days can be difficult, i.e. peak hours, when it's raining
4. Size
singapore is an island, for the first 3-6 mths you'll be busy exploring parts of singapore, but afterwards you might cover every parts of it....
But the good thing, you can explore the neighbouring countries afterwards.., Malaysia, Indonesia, Thailand etc
5. Crowd
Spore seems to be 'never sleeps' , there're still lots of people at MRT stations @ 11 PM (which makes me fascinated when I just come from Perth). It's late night shopping every day here in Spore as major dept stores closed at 9.30 pm everyday...
other than that everything seems to be generally the same, no problem abt meat here, beef are imported fr either Australia, NZ/ Brazil?
Easy to find australian Dairy products. Generally, no problem about food, you can find good quality & varieties of food stuff here...
Personally, I think Perth is not as stressful as Spore maybe bcoz of the personal space given...(in spore people mostly lives in condo, apartment while in Perth more to landed house...) & the pace of living...
