Ahh I remember your response to me before re not believing that I could emigrate without a degree and I pointed out that wasn't the case in my industry. You seemed to have commented again on post with a fairly negative repost. I suppose anyone can see the negatives but I'm asking for the positives in this case.
Firstly am 90% sure that your advice re career experience is not correct and believe the answer above yours was more pertinent.
I'm a man who plans everything and budgets for everything, always have and always will and as we are off on 3 relatively expensive holidays in the next 12 months and as previously stated I would be starting the process in my early 40's ( 38 atm)would negate the need for me to truly bust the bank by sticking some agents fees on a credit card ( something i rarely use) until I truly needed too so thought I would come on this lovely site for people's kind advice.
In terms of research done on the move I've covered all costs that I believe I will need but just to reassure you again;
We will have £1800 in excess income a month in 2019.
I will due to my profession be getting a job out there whilst in the UK unless we move to my more favoured location of WA in which case it may be slightly more risky. I'm hoping for an upturn in the economy which people within my profession tell me there will be in 2019 ( at least within rail anyway) and I have started seeing a number of design offices opening in Perth this year.
The job I will have does pay between $100k -$125k a year.
A number of companies have been known to fly family's out and accommodate them for up to 4 weeks in the past but if not I have priced flights for my family at £4800 ( they were the slightly more expensive Emirates ones as we would all love to go on the a380).
Not costed up the removals but have seen ball park figures of upwards of 10k for the entire process ( yes I know it can be more ).
Equity in my house by then would be between £200-300k. I'm blessed by house prices rising sharply due to hs2 arriving down the road . My favoured place to settle would be mindarie where decent sized houses with pools go from $500k +. House prices have fallen in WA due to the economic downturn.
We may also use some of the equity from our home as spare cash yes but (I know this is a guessing game) with the pound sliding the right away against the dollar (1.8) last time I looked it is approaching the heady days of my whv in oz in 2001 (2.3). I know Brexit may scupper stuff slightly but as said it would be a guessing game. In terms of people not being 100% and I'm sure we have had this conversation before my wife has said she doesn't want to stay in the uk but as you rightfully point out I know ideally she wouldn't want to move until her parents were not around. However she tells me that as long as we have the cash to fly back should anything happen she is good to go.
Teenage kids are a different story entirely , my kids atm are 4 & 8 so I may have been over egging the teenage bit but my daughter won't be far off. Luckily for them their parents make the decisions and as most kids do they will adapt and we being the parents will be safe in the knowledge that we've made the right lifestyle choice for them.
Not sure whether you have made the move yourself but really hope your not in the planning stage as your negatives really seem to out weigh the glorious positives. If you are in the planning stage then give it a go as what's the worst that can happen ? A move back ? Another 10-20 k squandered? Disney land is costing me 10k alone in April without the spending money ( expensive holidays are perks of the wife's job)
