Australian supplier, UK customer, EU physical location of supply - VAT guidance

I'm hoping for some guidance around VAT on invoices to be raised from Australia for a UK customer. We (an Australian company) are potentially overseeing the in-stadium media presentation of a sporting event in Spain, which is being organised by a company in the UK (who is our direct customer). I am having difficulty determining whether UK VAT would need to be added to our invoices, and whether the location of the event itself (EU) has any impact. Based on my research, I believe that under the B2B rules the supply would be determined to occur in the UK (as this is where the customer belongs) as does not qualify under the 'special rules' for place of supply, and therefore no VAT would be added to the invoice and the UK company would organise their own reverse charge. Any assistance or confirmation would be greatly appreciated.

Hi Christopher,
If you are providing services to a UK company from overseas then these would normally be accountable under the reverse charge procedure by the UK business customer.
Please see the guidelines below:
5. Reverse charge
The only B2B service taxable where performed is the admission to an event.
All other B2B services are determined under the general B2B rule.
Please see below:
9. Services supplied ‘where performed’
Thank you.
