The only thing for punters not to like about Australia since his 2,000 Guineas third has been his price, but I gather that he is now available at over 2.77/4 on Betfair, and has now reached a stage where he has to be of interest.
If you are allowed to bet, that is.
Because you don't need me to tell you that he has excellent claims coming into the race. In fact, they are so glaringly obvious that I can't really be bothered to go over them again.
But I have been told that I have to, so here goes if you have been living in a cave for the past month.
For a horse, by a Derby winner out of an Oaks winner, to do what he did in finishing third in an above-average Guineas obviously augured very well for his chances at Epsom.
And if he can translate even that level of form into this race he will probably win, let alone the likelihood that he will improve for the step up in distance, as you have to assume that he will.
He could easily be the superstar the stable have always believed him to be.
But things are rarely so straightforward, and if he doesn't get the breaks in what could be a messy race, or Epsom is hit by a late thunderstorm that turns it soft, then who knows how he will handle the conditions. He hasn't raced on testing ground so far.
I suppose if you wanted to crab the form of his Guineas third it was that he didn't go on and put the race to bed when bang in the firing line 1f out, as some may have expected a stayer to do. But I think if you did, then you are being a bit harsh on him as he was taking on some top-notch, specialist milers.
But he doesn't have that much in hand on form as it stands, and there are two or three in here whose chances I rate, and they ran in the Derrinstown at Leopardstown last month.
And it wouldn't surprise me at all were the Derby winner to come from that race, in which my mount Geoffrey Chaucer finished third to the disqualified Ebanoran and Fascinating Rock.
I suppose people will look at the video and think that because all three horses met trouble in running in a messy race and can be rated unlucky to varying degrees, then none of the trio strike as potential Derby winners. Particularly as none of them really put the race to bed in style when they had the opportunity.
But you have to give all three a decent chance - alongside the Guineas, it was clearly the best Derby trial - and the more I look at the video, the more I like Ebanoran, who was disqualified after winning. And what struck me most about him was the turn of foot that he showed 1f out to go clear.
It is a given that you have to stay to win this race, but it is also crucial that they have speed, too, and tactical pace. Workforce had it, but Carlton House just lacked that change of pace where and when it mattered and that was what cost him a Derby win, not a lost shoe.
I think that Ebanoran could be the horse with the best change of gear in this race, and that makes him very dangerous. I think that he is primed to run a massive race on Saturday.
Being an Oasis Dream, I do have a concern about his stamina, but the distaff side of his pedigree is packed with stayers, and if he does see out the trip, then I think he is a big, big danger to all. And his hanging at Leopardstown wouldn't overly-concern me.
Can my horse reverse the form? Of course he can, as we are dealing with unexposed horses here. Geoffrey Chaucer clearly didn't get the run of the race that day, is open to a lot of improvement, and I don't think there are too many doubts that he will get the trip.
Aidan seems very happy with him at home - though I don't believe those "wonder gallop" rumours with Australia a couple of weeks ago for a minute, and nor should you - and I go in there with a live chance.
But if you fancy Ebanoran or Geoffrey Chaucer, then it stands to reason you must give Fascinating Rock a chance too, though he is drawn wide in 15 and he will need plenty of luck in running coming from behind.
Orchestra, who I rode to win the Chester Vase by a nose from another promising horse in Romsdal, is not a horse to be underestimated, either.
He travelled really well there and I was mindful of not being too hard on him that day, as I believe Aidan had left a fair bit to work on and I didn't want to punish him with the bigger races in mind.
In fact, I think I got away with it there, as when I pulled up my first thought was: "Bollocks, I may have got beaten here".
But he did it very nicely, and there should be plenty more to come from him. I haven't sat on him since - and horses can change an awful lot in a month at this time of year - but if he has blossomed then I give him a decent each-way shout.
There are two ways about looking at Kingston Hill's Guineas run. Yes, he ran a good race in eighth, but was it that good?
But maybe I am being far too harsh on him. He is the only Group 1 winner in the race after all, and one who should improve for the trip. His connections will certainly be hoping that those Saturday thunderstorms materialise, and you clearly can't write the second favourite off.
A lot of people are suddenly viewing the Dante in a better light after The Grey Gatsby won the French Derby for me last weekend.
But that's probably a selective assessment at its worse, as the sixth horse, beaten only 4 ½ lengths at York, was beaten further than that in a Newmarket maiden last weekend. You don't hear Arod and True Story's supporters headline that fact, do you?
No, you have to judge the horses on what they did at York, rather than what others have or haven't done since. And to me True Story, who really impressed me in the Fielden and looked a real Derby prospect that day, looked a bit too keen and I'd be worried about him lasting home.
I think Arod will improve for the step up in trip and he looks a real good prospect. My concern for him is whether this will come too soon for him, and I personally view him as more of a potentially top class 4yo next season once he has more experience and know-how. And, although it would be stupid to dismiss any unbeaten horse, I am not really drawn to Western Hymn.
If Australia doesn't perform for whatever reason, then this is up for grabs, and Geoffrey Chaucer is certainly one of the most likely to benefit. But I was really taken by Ebanoran at Leopardstown, and for me he is definitely no 20.019/1 chance in this.
