Yet another 5 star review for Mark from Worldwide Advisory. As a Swiss/Australian living and working in Switzerland for the past 8 years, I needed advice and assistance on my Tax returns and paying off my HELP Debt. Mark is professional, knowledgeable, clear, and trustworthy. Dealing with the Australian tax system, especially while living overseas, was for me a very confusing and stressful process. I am grateful to have found Mark and would recommend his Accounting services to anyone.

Mark has been a very helpful person, he was very kind and helped us with our tax return, making it very easy. I know I would 100% repeat with him if I had to do another procedure like that.

Highly recommend speaking to Mark if you're moving overseas. Was very clear and concise in his advice and was always more than happy to help with my endless badgering of tax residency questions. He made everything very simple & easy, and was always very quick to reply.

I recently had the pleasure of a 1 hour online tax session with Mark, and have came away with only great things to say about the service provided. Whilst I was navigating the minefield that is international tax (being an expat), Mark discussed my unique situation and provided concise / concise recommendations to support my financial planning.

I needed all the help i could get, and Mark certainly provided that. Much less stressful than trying to work out how to do my taxes by myself whilst living abroad.....

I highly recommend a chat with Mark, as tax is very complicated in Australia and in my case becoming a non resident.It is clear that Mark is very knowledgeable and has a good understanding on how things work. I look forward to continue working with him.

I'm based in Germany and being paid through an Australian company. Mark Mansour gave some useful free advice as a great starting point to understanding my tax situation in Australia, and gave me a contact for help with the German side of things too. I'm confident he'll be able to help me come tax time.
