Hi Stephen,
What makes you believe that AHR Wealth Management are bona fide?
I can see from their LinkedIn page they are based in Dubai and do not have an office in Australia. This is a huge red flag. These 'providers of cross border solutions' usually place themselves in countries such as Dubai, Hong Kong, UAE due to the lack of regulations. In terms of providing advice should you decide to stay in Australia, I almost guarantee they cannot assist with this, as I do not believe they are licensed to provide advice in Australia. Which also means they are not regulated.
In my opinion, this company does not look legit and I can predict the advice you will receive. They will recommend a SIPP, with some insurance bond within this to hold your investments. The insurance bond, not only is it not required, but will pay the adviser an upfront commission - that you will then pay over the lifetime of the bond.
I completely agree with the above. If you have been cold called in regard to this (usually finding your details on LinkedIn, with a link to the UK), be extremely careful.
