Cash and Company was an Australian television period adventure series, set during the Victorian gold rush of the 1850s. The original series consisted of 13 one hour episodes, filmed in colour and on location in rural Victoria.

Production began in July 1974 and the series premiered in Sydney on the Seven Network on 26 May 1975, in Melbourne on 29 May, and in Brisbane a few weeks previously. It was also was screened at the Cannes Film Festival, and was sold to Sweden, Holland, Yugoslavia, Ireland, Norway and Nigeria.

It was produced by Homestead Films, a TV production company set up by Patrick Edgeworth and Russell Hagg, who had worked together at Crawford Productions on Matlock Police. Edgeworth's brother is the musician Ron Edgeworth, who is married to Judith Durham of The Seekers.

The episodes dealt with the adventures of bushrangers Sam Cash (Serge Lazareff) and his partner Joe Brady (Gus Mercurio) and a helpful widow, Jessica Johnson (Penne Hackforth-Jones). Cash and Brady were fugitives, constantly absconding from the authorities, led by the corrupt police trooper Lieutenant Keogh (Bruce Kerr). Other regular and recurring characters included Jessica’s father in law (John Frawley) and her servant, Annie (Anne Scott-Pendlebury).

The series was shot almost entirely on location at Sunbury, Victoria, the same area where Mad Max (1979) was filmed.

Lazareff decided to leave at the end of the first series, when a second series was still in the planning stages. His character was replaced by Ryler, a former bounty hunter, played by Gerard Kennedy, a former cast member of Division 4. Ther Ryler character had appeared in one episode of Cash & Co., and Kennedy was recruited to replace Lazareff after Seven told the Homestead Films that they would not buy a second series unless the popular Logie-winning actor was cast in the new series.

The series was renamed Tandarra, to avoid confusion with the first series and the "on the run from the law" story-line was removed. The character of Keogh was also dropped, and the character of Annie (Jessica's maid, played by Anne Pendlebury) only appeared in one episode. The character of Sam Cash was not mentioned at all in Tandarra, and all flashback sequences from the first series removed any reference to him.

Although the series title is taken from history, the story, events and timeline are of no relation to real life Australian bushranger, Martin Cash, whoes gang went by the name of Cash and Co.

The series was shown in the UK by London Weekend Television (LWT) before being it was seen in Australia.
