The Middlesex versus Nottinghamshire fixture will see me come up against my former county for the first time, so it's going to be really interesting.
I had five great years at Trent Bridge, during which I played with the majority of the current Notts team. They're really great guys and I got along really well with them all.
Luke Fletcher in particular is a standout character without a shadow of a doubt. He kept things light-hearted when we were doing tough days in the dirt. He could always come out with something to make you laugh.
When he's running in on Sunday and I'm facing him, I'm not sure I'll be able to keep a straight face, but it will be a good battle.
I'm also looking forward to being reacquainted with my Hawthorn Football Club mug, which I took over to Trent Bridge in my first year and it's been there ever since.
Steven Mullaney sent me a tweet and a text when he was having a cup of tea out of it, so it's nice to know it's still going strong.
If Chris Read brings it out to the toss with him I'll gratefully accept it, then it will be down to the serious business of the game, which I hope will be the start of scoring some runs for Middlesex on the back of an Australian summer that exceeded all my expectations.
For me, it's been by far my biggest season in terms of runs scored and it was terrific to have success as a team with Western Australia by winning the Matador BBQ's One-Day Cup and finishing the Sheffield Shield season as runners-up.
I'm not entirely sure what the turning point was in my game, but to be consistently scoring big runs was something I'd been building up to for a few seasons and I'm over the moon to have been picked in the squads both for the West Indies tour and the Ashes.
With Mike Hussey and Chris Rogers in recent times, the selectors have shown that age isn't a barrier if you're scoring runs at domestic level, but I did have doubts about whether I would ever get the opportunity of playing Test cricket for Australia.
Now I've scored enough runs to get an opportunity, hopefully I can get a game at some stage. It would be something really special to walk out at Trent Bridge in a baggy green cap. Hopefully I'd get a couple of claps off the members for that too.
