The UK does not formally restrict exports but it didn't export a single dose to the EU despite AZ telling the EU that they would. This lead to the export controls the EU put in place where the EU can forbid exports into countries that don't export themselves. AZ exported 9 million doses into the UK, the UK didn't export a single dose back.

The UK most likely sent them to Australia because Italy blocked AZ exports to Australia.

The AZ doses that the EU did not receive were from plants based in the EU run by European companies fulfilling AZ production. The UK government even invested £55m over a year ago in one such EU-based plant to bring its capacity up after the Dutch government didn't.
