That is all because you do not have the "Australian" working experience and do not recognize our malaysian working experience, but there are exceptions where in industries which they have no one or no choice then only they will take into account. Therefore the best way to maintain your whatever position/experience is through employer transfer.

What they mean is that you need to have working experience in Australia. No matter how well you did in Malaysia, it doesn't mean you can qualify for the job you want in that industry.

Yes, but you'll need to proof your skills. For your case you'll have to write an CV to ACS (Australia Computing Society) to get it certified, best if you could take one of their certification. It is also a must to have all those IT certifications from Microsoft, Cisco, Linux, VMware etc.

Agree. Took me 2-3 months to look for a job. Thanks to my ex-boss. Without any reference, could easily take 6-18 months.

Also need lots of income to sustain, I would suggest minimum Rm20k to sustain for 6 months until can find a casual job.
some basic breakdowns in AUD

Rental Deposit(security bond): $1200
Rental Per month: $1000
Internet/Bills per month: $100
Food/Drinks(Eating home): $600

Extra:
Eating out(Cheap Food): $10 per meal
Transportation(2 ways in same zone): $7

Looking for casual job is not easy anymore, not to mention professional job.

How's the job market there? WA property/rental is carzy right now, average $550 per week!

You wished, not furnished of course!

There's no longer subclass 175. Replaced with 189. The difference is that you have to go thru the skillselect system which you have to submit your expression of interest (EOI) and wait for their invitation.
The trickiest part is the medical. If your medical fails you, everything gone.

I did mine at RM 20k. Yes, i got mine January tis year

Well my friend, it's not something you're thinking that way. We've got something which really have to let go, like friends and family. I'm not from rich family, but Ozzie require my skills so thinking of earning some to send money back. It's a life mission goin there. Who wants to migrate if the government is fair and clean?
It ain't like what people think that other country is greener. 
We're something like a tree planted and have to pull out the root planting on the other place and start all over again. Stress on putting food on the table is there and we really rely heavily on own community.
Finding job is a big issue, i guess anyone who migrate will telling you the same thing.
Why am i migrate? For the sake of children education. Malaysia give me no option in this, especially the national budget which we're not given a shit for the family.
We're trap in the middle income. No eligible buying low cost housing, watsoever aid, not rich enough to purchase a median home. There's not many option at all.
I paid tax and gain nothing here.
If you're skilled, you could check it out on DIAC website. Maybe you're eligible too, who knows? I did that way also encouraged by someone.

Sorry, need to rephrase my words. Currently still looking for job. I'm in construction industry. Plenty of jobs in my line, hopefully will get employ within months.
