Director & Head of

Dean R Sharrar

Tony’s career spans 30 years of corporate treasury roles with major companies, primarily in the energy sector together with a number of current and former board positions. Extensive governance experience has also been gained in both the private sector and government, especially in organisational restructures, project development and major divestments and acquisitions. He holds the FINSIA Diploma in Applied Finance and Investment and is a graduate of the Australian Institute of Company Directors.


Tony has represented Barrington Treasury Services in Australia since 2013 and has also held the following roles:

  • Director of Maleny Credit Union (an APRA-governed, Australian authorised deposit-taking institution) and member of the Risk and Audit and Finance Committees
  • CEO of Maleny Credit Union during the 2020 sale process to Queensland Country Bank
  • Director of Commercial and Treasury Services – own company specialising in advisory assignments across most industries.
  • Chair of True (formerly Family Planning Queensland), implementing a commercial focus to growth areas of the business including re-branding the organisation.
  • Chair of Queensland Poetry Festival, overseeing continued growth into its 20th year attracting local, interstate and international visitors to the festival and related events.
  • Director of Perpetuwave Power, a wave energy development company.


Tony first specialised in corporate treasury at the Adelaide Steamship Company and was Treasurer during its refinancing and asset sale period. Relocating to Adelaide after the float of Woolworths from the Adsteam group, he established and ran a new treasury function for Elders Limited following its ASX re-listing from the Fosters Group and was part of the Elders Rural Bank establishment team.

Subsequently, the Queensland Government-owned generator Tarong Energy recruited Tony as Treasurer.  Providing around a quarter of the State’s electricity, Tarong sought additional capacity and fuel supply, completing a number of transactions with Queensland Treasury Corporation and with joint venture parties.  During this period, Tarong also developed and built South Australia’s first wind farms.  Tarong was later combined with Stanwell Corporation to provide around 45% of the State’s electricity supply.  The Treasurer role then expanded to include a commercial review of all capital and major operational investments.
