Split address from one cell to have street number/name and suburb/state/postcode separated

I'm after a formula or some formatting trick to split up the address in the attached sheet. As you can see, the addresses have come through from a database in one cell, instead of a separate cells for the street line and the suburb line, making it difficult to merge for mailing.

eg. the address are coming through to the merge like this;

Joe Bloggs
3/119 newtown street sydney nsw 2001

When i need them to look like this;

Joe Bloggs
3/119 newtown street
sydney nsw 2001

Thanking you in advance

My thoughts too. If you did not know, how you you decide how to break up these...
71 GAN GAN ROAD ANNA BAY NSW 2316
UNIT 1 33 PARRAMATTA STREET CRONULLA NSW 2230
CARE DEFENCE REGION EST ORG & CORP SVCES INFRA - CNNSW RAAF BASE
RED HILL YEOVAL NSW 2868

Remember, to excel, they are all just random letters and numbers
