Here we are. In the middle of filling in a 457 at the moment, this is the instructions re de factos (copied and pasted) and as you can see its six months. So all good!
----------------------------------------------------------------------

If you are not married and are in a de facto spouse relationship, please provide a short paragraph summarising your relationship, eg when and how you met, when you started living together and other commitments you have made to each other.

You will also need to provide copies of documents to evidence living together (for at least 6 months).
Suggested documentary evidence to show you are in a de facto relationship includes:

• correspondence addressed to yourself and/or your spouse at the same current home address/previous
addresses;
• joint loan agreements for real estate, cars and/or other major assets;
• joint residential rental agreements and receipts;
• joint bank accounts or insurance policies;
• utility accounts;
• wills, superannuation or life insurance policies showing the name of beneficiaries;
• evidence of ongoing communication during periods spent apart; and
• if no other documents are available, statutory declarations or signed statements from both parties
confirming the length and nature of the relationship.

Please note it is NOT necessary to provide each item listed, 2-3 documents are sufficient.

However, please ensure you provide documents demonstrating you have been in a de facto relationship for at least 6 months, for example selected (2-3) rental receipts covering the period you commenced living together to the present.

Good luck, Gail
