Other casino outings on the taxpayer purse were more restrained at 0, .28 and .88.
The records showed that Defence's spending on dating and escort services was generally more expensive than gambling, with charges ranging from 8.58 to just 41 cents.
Of the total ,160.43 spent on casinos and escort services over three years, the Department has since recovered 9.45.
In addition to the Visa Purchasing Cards, it also runs 70,000 Diners Travel cards used for more than $260 million charges a year.
The audit office strongly criticised the department's management of the cards.
In response to the audit, Defence adopted "new governance arrangements for credit card management" at the start of 2016.
Defence has released a summary of payments under Freedom of Information laws for "gambling transactions" and "dating and escort agencies" in 2013, 20.
The credit card statements showed nine matching transactions during the period.
Offsetting the escort and dating expenses, Defence accounting shows '-1.58', suggesting one payment was reversed last year.
Cards were used on four occasions for "betting, gambling chips" with the biggest charge worth more than 4.41 in February 2013.
In January this year the department asked its corporate credit card providers to put a "block" on any further charges in the gambling and dating categories, "thus stopping the possibility of future expenditure being incurred against such merchants".
Blocking had been recommended in a recent investigation by the Australian National Audit Office, which found Defence had never put any merchant blocks on its 7,378 Visa Purchasing Cards, even though more than million had been charged over three years on category "7997 — Clubs; country clubs, memberships, private golf courses, entertainment".
Blocking automatically stops a transaction whenever a merchant tries to charge using the category code.
As a large and dispersed organisation employing 19,000 civilians and 58,000 uniformed personnel, the Defence Department operates more than 100,000 credit and transaction cards for travel, purchasing and taxis.
