Christine Forster, the lesbian sister of Australian Prime Minister Tony Abbott, is engaged to her girlfriend Virginia Eduards. She popped the question in March on a trip to Broken Hill.

However, Ms Forster does not want to hold the same-sex wedding ceremony in New Zealand or other countries where gay and lesbian marriage ceremonies are held. The Liberal Party councillor representing Sydney would rather hold the rites in the capital of New South Wales, hoping under a federal marriage act.

But she is resigned to the fact that it could be a long engagement and it may take long before such an act is passed because even her brother is against same-sex marriage. Now she is counting on a NSW act.

"For us it's really important that we are married in our home and that our marriage is recognised in our home, which is here," The Sydney Morning Herald quoted Ms Forster.

Not wanting to be disappointed, the PM's sister who is actually a mother of four children, said she would only begin to make wedding plans when she is sure that she could enter a legal union and there is a change in law.

And despite Mr Abbott's opposition to gay unions, she said her brother and his wife, Margie, will surely attend their same-sex wedding when it happens. To add gender equality in her wedding day, Ms Forster said rather than have bridesmaid, they will instead have drag queens.

The Australian Capital Territory is slated to vote on Tuesday on a same-sex marriage bill after the ACT government announced on Monday that it would change its marriage equality bill to avert being defeated in the territory's High Court. The amendment involves changing the bill's wording s that it would clearly identify the law as being crafted for same-sex couples only.

The ACT government said the bill is slated for debate on Tuesday and it expect to be passed on the same day, notwithstanding a request to the ACT Legislative Assembly from seven Christian, Islamic and Jewish leaders to defer a vote and send it to a committee for investigation.
