Thank you to everyone who commented, very much appreciated. With the figures we had from researching everything, we had a round about sum of $20k...then allowing for $4/5k agents fees so not too far off what we've been quoted I guess. @Dukeninja, thank you for the ANMAC tips, very useful & we will begin the process of that ourselves as it was the initial cost of $4500 through the agent that scared me to be honest!! We already have most of the uni info, just awaiting a letter with breakdown of hours from them now. Received reply from agent to confirm what has been generally said on here: "The estimate fees is for Assessing Body, State Nomination Fees, Government Fees and our service fees, it does not include registration costs as we are not able to assist you with registration, medicals costs, English tests costs etc" Thanks again and I'm sure I'll be back on here for advice soon!
