World Cup, and later sacked the forwards coach Andrew Blades. Scrum coach Mario Ledesma was recruited to the Waratahs and began working on scrummaging with the Wallabies players that were in New South Wales. Brumbies head coach Stephen Larkham was brought in as backline and attack coach for the World Cup. Nathan Grey was appointed as defence coach. In the lead up to the 2015 World Cup, Cheika is credited for inventing Giteau's law which enabled overseas based players to play for Australia. During the 2015 Rugby Championship, Cheika made multiple changes to his side for each match despite the Wallabies' winning form. They opened their campaign with a 24–20 win over South Africa, winning in overtime with a late try from Tevita Kuridrani. They beat Argentina 34–9 a week later to set-up a decider with New Zealand in the final round. It was during that All Blacks match that Cheika started two specialized opensides for the first time since 2010, and they were both influential in the Wallabies 27–19 win. The win sealed the Rugby Championship for the Wallabies, their first ever Rugby Championship title, although including the former Trinations format it was the Wallabies fourth title since the competition began 1996. The Wallabies also achieved a 100% win rate for the first ever time in either format. However, the Wallabies failed to win the Bledisloe Cup, losing to New Zealand 41–13 in Auckland a week later. Despite having only been in charge of the Wallabies for a year, Cheika led Australia to the 2015 Rugby World Cup Final. They topped Pool A with victories over Fiji 28–13, Uruguay 65–3, England 33–13 and Wales 15–6. They narrowly beat Scotland in the quarter-final winning 35–34 after a controversial last minute penalty. They beat Argentina 29–15 in the semi-final to reach the final against the All Blacks. The Wallabies went down 16–3 at half time, but fought back in the second half to trail by only 21–17 with 10 minutes remaining. However a drop goal, penalty and a last minute try saw New Zealand claim an historic 34–17 victory. On 1 November, Cheika was named 2015 World Rugby Coach of the Year, becoming the first Australian coach to claim the title since Rod Macqueen in 2001, and the first non-New Zealander coach to win it since Ireland's Declan Kidney in 2009. 2016–2017 In 2016, England toured Australia for a three-test series,
