Richmond Football Club From 2010 to 2017, Liddle was the chief customer officer for the
Richmond Football Club. His duties in that role included "ticketing, retail, licensing and corporate revenues" as well as managing Aligned Leisure, a subsidiary health and recreation business.
Carlton Football Club Liddle was appointed CEO of the
Carlton Football Club in November 2017. Liddle was able to grow the Blues' financial arm considerably during his tenure and under Liddle's leadership as CEO, the Carlton Football Club cleared historical debt, significantly grew membership and commercial revenues, as well as the introduction of new non-traditional revenues. On 10 September 2021, Liddle parted ways with Carlton after he was sacked from his position as CEO. The club came to this decision, after an extensive review of the club's football operations due to the club's disappointing
2021 AFL season with poor on-field results, where it was determined by the club, that the gaps between on and off-field performance were too large for Liddle to maintain his position as CEO. Liddle was then replaced by
Brian Cook as Carlton's CEO.
Incrementum Advisory Group Liddle later joined the Incrementum Advisory Group as director, where he consults to some of the country's biggest sports, sporting clubs, universities and LGA's to drive growth for the clients. ==References==
