FORMER Yeppoon man Luke Kalache will have to remember Queen Elizabeth II is not one of his mates from Down Under when he greets her in a once-in-a-lifetime opportunity this week.
Wife Fiona Kalache says, knowing Luke, he'll probably say "G'day Liz".
Aside from minding their P's and Q's in front of the Queen, the man from Outback land also has to follow strict rules and protocols.
For instance, the couple cannot pass their formal invitation on to anyone else as security checks have already been carried out on the people invited.
If you could not make the royal party, you had to return the invite.
"When the invitation came, it had various instructions with it, such as dress code, which was hats and dresses for ladies and morning or lounge suits for men," Fiona said.
"It also listed the forms of identification we had to bring; such as passports and driver's licence.
"There were also strict instructions about no photography... from meeting Princess Anne, I also know there is etiquette such as not to speak until you are spoken to."
Fiona understands the Queen is attending the garden party, but she is unsure if any other royals will be with her.
The one-off invitation came after Fiona was nominated for her work with young people in the community she lives in - Lochgilphead, Argyll.
She manages a charity called Mid Argyll Youth Development Services, which works with people aged between six and 25 years old to provide a range of recreational, educational, social and informal learning opportunities.
Most of the young people come from rough backgrounds or are in difficult circumstances.
How Fiona came to be nominated was a mystery but she was just about to throw her invitation into the junk mail pile.
"I was at home one Saturday morning and Luke collected the post and said 'there is a really posh envelope here addressed to you, it looks like an invite or something'.
"When I looked at it, it had a Buckingham Palace stamp on the front, which I thought was strange.
"Inside was the formal invitation with all attached documents... it said, the Lord Chamberlain is commanded by the Queen to invite Mrs Fiona and Mr Luke Kalache to her royal garden party. To be fair I was not up on garden parties and had to look it up on the internet."
Luke's many years training and working as a tiler, for his brother-in-law Duwayne, paved the way to set up his own business in Scotland.
The royal party
The Queen's Garden Party will be held on Tuesday, July 1.
