Scheduled maintenance
We’ll be doing planned maintenance from 5:00 pm Friday 28 November to 9:00 am on Monday 1 December (AEDT).
During this time and for a short time afterwards, updates to ABNs on our website may take longer than usual.
If you’ve registered a new ABN or updated an existing one, it might not appear straight away. If your ABN isn’t listed yet, please check back later.
Thanks for your patience!
