Assume your profession is highly demand here and meet up all the requirements
Look for these options:-

1) DIY
you'll save heaps of cash like 50%? You'll need to make some phone calls, emailing and sort your documents. I would say the whole process you'll like time spending 80%. If you got time would be the best.
advise is, please!!!!!!!!!!!! read their DIAC website thoroughly! every info and every word and understand it! don't be lazy

2) Agents
you'll paying $30k in total? Agents are for those who dunno a shit of english. buta2 dunno how to apply at all. anyway, i applied thru agent too... Totally tied up with work! No time, worked like cow back in KL for 10hours everyday....YES! EVERY SINGLE DAY!

engaging R*****d. they're sucks. even i got mine thru them but their service is ganasai. my case is easy and straightforward. i did my homework and screw them few times so end up getting my PR less than 6 mths.
they'll squeeze you at the end for some more cash. oh, they know you got money and they'll squeeze your ba.....er...imean your neck for more. However, i paid $20k for the whole process....everything.
189 gives you better remote to work any part of australia including the cave also....haha....no cave here, sorry. if you wanna live in metros like Syd or Melb, this is what you need but your points nd to at least 60p.

if you're short, nvm, pay $$ for state sponsorship and get extra 5p but might be living in the city you like say....sangkala place like Darwin or Perth? Drinking beer with kangaroo or koala.

DO NOT ENGAGE overseas agent! you'll not able to meet them face to face and your $$ will drain down the shithole. I knew someone back there with good repu but dunno how's it now coz it might be different now or else you'll curse and screw me kaw2.

Anyway, good luck!
