Looking back on a great weekend in Oz
This blog comes to you from 39,000 feet above Australia.
I can scarcely believe it but as I write, despite having been on the flight for four hours, we're still crashing through the sky above the country.
I'm glancing out of the window at the Northern Territory, an undistinctive, sandy landscape as far as I can see. And I thought Norfolk was flat!
This is a true F1 flight, with every seat filled by someone who works in the sport. Mercedes team principal Ross Brawn is in the first row, Nico Rosberg's race engineer Jock Clear is to my left along with Hispania Racing driver Karun Chandhok, who is undoubtedly one of the coolest customers I've ever met.
To a man, they're either sleeping or looking like they will be at any minute. Flights shared with F1 teams are sometimes like an 18-30 holiday in the sky, particularly if a team has something to celebrate, but not this one - we're all pooped!
The reason the Australian Grand Prix is particularly tiring is the combination of jet-lag and the late race start time. Let me explain how this weekend panned out.
You get hit by a real lull mid-afternoon because your body clock remains convinced 5pm is actually 6am and is totally unable to compute why you are sitting next to some tennis courts in Melbourne drinking instant coffee, so it tries to force you into a deep comatose sleep.
We managed to stave off the yawning by trying the 'Tim-Tam-Slam'. Tim-Tams are famous snacks out in Australia and the 'Slam' is where you drink your tea by using them as a straw. The fun soon spread to a Twix until Mark Wilkin, the boss, and I burned our tongues... Game over.
An hour after we'd come off air with the qualifying show on Saturday, the office looked like a a meeting of narcoleptics anonymous as we all worked away with lolling heads and droopy eyes.
Once you survive that lull, it's a case of forcing yourself out for a quick dinner, before getting back to the room about 11pm, when you crash out instantly. I then wake up feeling like I've had eight hours' kip, and look at the clock to find it's only 2.30am. It's then a combination of reading, watching shopping telly, or typing the script until breakfast was ready at 7am. My body just didn't want to sleep.
So you can understand that after little sleep, covering the race, then getting away from the track about 9pm, any requests to go out fell on deaf ears as far as I was concerned on Sunday. Never has a hotel bed felt so comfortable, even if I am considered a lightweight by the whole team.
One man who can't be considered a lightweight is Eddie Jordan. His energy is incredible as he races from working for us to rocking out some club in the city centre with his band every evening.
Mind you, we've actually worked out how to keep him quiet. We just need to take a fairground ride with us everywhere we go! If you were up early on Sunday (and well done if you were) you will have seen the video of myself, EJ and David Coulthard watching grass grow and paint dry as a jokey reference to the Bahrain Grand Prix.
It ended with EJ and me being pinged into the air - and for an entire minute he didn't say a word. A whole minute. Without even a peep from EJ! Sadly, I just don't think the ride would slip under the plane baggage allowance.
Seriously, though, I genuinely hope I have EJ's energy and passion when I've seen and done as much as him.
He was standing in our less than salubrious office on Sunday morning saying to our director, Richard Carr: "Is this shirt too rock and roll for BBC One?". The answer should be no every time - if one man can pull off electric blue with white flowers it's EJ.
The team were beaming like they had won the title, JB was running around with snappers following his every move just like in Brazil last year, and the whole paddock gravitated towards the McLaren hospitality area.
I've seen a few F1 wins at close quarters and the atmosphere this time was unique. If you missed the F1 Forum on the red button then you can watch it again here on the BBC iPlayer. It was great to be in the heart of the party and hear from the man himself. I'd like to know why you think it was such an emotional win.
It felt as if we were witnessing a watershed moment in Button's career. But was it that the doubts about his decision to join 'Team Lewis' had been blown aside? The fact he hadn't won since Turkey '09 and it was a huge weight off his shoulders? Or perhaps the realisation that the new MP4-25 is a decent race-winning car?
But he was graceful enough to congratulate Button and actually drove an incredible race himself. It's also worth taking a look at this video embedded below. We shot it in Woking just a few days before the season started. What it doesn't show is that Jenson was even more relaxed off camera.
Right, a progress-check.
We've just crossed the Australian coast and we're now over the Timor Sea. Chandhok just stopped by, too, and we discussed the weekend from his perspective. He was saying that in getting a Hispania car to the finish of the race on Sunday he drove a third of the laps that the new team have ever managed. Incredible effort.
Right, I really am just about the only person left awake on this plane so I'll try to grab some shut-eye.
I'm really pleased all you early birds got your reward this weekend. Once again, the sport delivers a truly cracking race just as we needed it!
Now we head west to Kuala Lumpur. And if we thought Melbourne was wet, just remember Malaysia last year.
By the way, I'll be a doing a Q & A session here on the BBC F1 website shortly. If you'd like to get involved then just post a question below! We'll answer as many as we can. You can also follow me on Twitter.
