Tax Working for an Australian Company whilst based in the UK

Hi, I'm UK/Italian citizen that has a full-time job and is resident in the UK. Recently a company for which I worked in Australia (I spent a couple of years in Sydney, with working VISA 10 years ago) contacted me for a remote job that I can do in the UK. It will be a casual job contract (I have a fulltime job here in the UK), but it is not clear to me if I should pay taxes for Australia or for the UK. They will eventually pay me in the Australian bank account. If it is Australia, I have to fill out a form, but if it is the UK what should I do and what eventually does the company need to do?

Hi

As per Article 14 of  the UK/Australia Double Taxation agreement, as a UK resident working remotely you will continue to pay UK tax on the income received from your Australian employer.
If any tax is deducted by the Australian tax authority, you can claim Foreign Tax Credit Relief in the Foreign pages (SA106) of your Self Assessment tax return. 

Thank you
