AIDAN O'Brien's 2018 St Leger winner Kew Gardens has been assigned the top-weight of 58kg for the AU$8 million Lexus Melbourne Cup, known in Australia as 'the race that stops a nation'.

Racing Victoria's (RV) Executive General Manager - Racing, Greg Carpenter, unveiled the weights today for Australia's two richest handicap races, the Melbourne Cup and the AU$5.15 million Stella Artois Caulfield Cup, which was won last year by Godolphin's Best Solution.

Cross Counter, who surged to victory in last year's Melbourne Cup for his trainer Charlie Appleby, will carry 57.5kg this year as he bids to become the first horse since Makybe Diva in 2005 to retain his crown.

The 6.5kg increase from last year's weight of 51kg is the joint second highest progression in the weight allocated to a Melbourne Cup winner since 1970, with only Gala Supreme - in 1974 - receiving a larger increase of 8.5kg.

Joseph O'Brien, winning trainer in 2017, has a trio of Master of Reality (55.5kg), Latrobe (55kg) and Twilight Payment (55kg).

The Caulfield Cup, the world's richest turf handicap over a mile-and-a-half has the Godolphin pair Avilius and Hartnell as top-weights. The James Cummings-trained pair were both imported from Europe to race in Australia, where they have registered a combined six wins at Group 1 level.

With differing top-weights across the two Cups, the majority of dual entries have received 0.5kg less in the Melbourne Cup than the Caulfield Cup.

Avilius has been handed 57.5kg in the Melbourne Cup, with brilliant mare Lys Gracieux - trained in Japan by Yoshito Yahagi - next in the weight scale on 57kg.

"Kew Gardens was the world's joint highest-rated stayer alongside Stradivarius last year, he was a dominant winner of the 2018 St Leger at Doncaster and so is a worthy top-weight among the 152 entries for this year's Melbourne Cup," said Carpenter.

"Cross Counter will carry 6.5kg more than when he won the Melbourne Cup, which is the same increase as Let's Elope in 1992; but given the nature of his victory last year and the natural progression in the weight-for-age benchmark from a three-year-old to a four-year-old, I felt it was an appropriate penalty to impose.

"In the Caulfield Cup, Avilius and Hartnell have both proven themselves at the highest level, and thus have been assigned equal top-weight among the 145 entries. In the past 12 months, Avilius has won two Group 1 races at a mile-and-a-quarter or further and was Australia's highest-rated stayer, while Hartnell has maintained his place among the nation's elite performers.

"Inevitably the internationals will again pose a formidable challenge to the locally-trained stayers, with the first three home in the 2018 Melbourne Cup all set to return to Melbourne this year; but if the likes of Andrew Ramsden winner Steel Prince and Adelaide Cup winner Surprise Baby can maintain their form throughout the spring, I'm sure the visiting horses will have a real fight on their hands."

The weights allocated to other notable entries are as follows:

• The 2018 Melbourne Cup placegetters Marmelo (Hughie Morrison) and Prince Of Arran (Charlie Fellowes) both have the same weight as they carried 12 months previously, with 56kg and 53kg respectively. Prince of Arran has 53.5kg in the Caulfield Cup;

• Northern hemisphere three-year-olds have won the past two Melbourne Cups and the equal highest weighted on 52.5kg are Irish import Constantinople (now trained by the Lindsay Park team of David and Ben Hayes and Tom Dabernig), German Derby runner-up Django Freeman (Robert Hickmott) and Lonsdale Cup placegetter Il Paradiso (Aidan O'Brien). The former two are also nominated for the Caulfield Cup, and have 53kg;

• Six-time Melbourne Cup-winning owner Lloyd Williams has multiple runners in contention for a start in the 2019 edition, including the Joseph O'Brien-trained trio of Master of Reality (55.5kg), Latrobe (55kg) and Twilight Payment (55kg); plus Homesman (56kg), Johannes Vermeer (55kg) and Yucatan (54.5kg), all formerly trained by Aidan O'Brien but now prepared locally by Liam Howley;

• Last-start German Group 1 winner Danceteria (David Menuisier), one of two late entries for the Caulfield Cup alongside Constantinople, has been allocated 56kg for the 19 October feature;

• Soon-to-arrive imports Mirage Dancer (Trent Busuttin and Natalie Young) and Southern France (Ciaron Maher and David Eustace) have also been allocated 56kg in the Caulfield Cup - 0.5kg more than the Melbourne Cup;

• The Australian Bloodstock-owned Ebor Handicap winner Mustajeer (Kris Lees) has 55.5kg in the Caulfield Cup and 55kg in the Melbourne Cup, whilst runner-up Red Galileo (Saeed bin Suroor) has 53kg and 52.5kg respectively;

First acceptances were also taken today for Australia's weight-for-age championship, the Ladbrokes Cox Plate, which will be run at Moonee Valley Racing Club (MVRC) on Saturday, 26 October.
