Hi @Leo111,
As you are completing a service (as opposed to selling a good), it comes down to when the service was done, not the invoice. As you were not registered for GST in June, and if you're annual turnover is below the $75,000 threshold, you are not required to charge GST.
If you're above the threshold in June, and your registration date is 1/7, you would be required to charge GST and potentially back date your registration date.
