In a statement, the ARM said it had been informed by Typeform on 2 July that it was among the company's clients whose data had been compromised.
As iTWire reported, the Tasmanian Electoral Commission said on Monday that its voter data such as names, addresses, email addresses and dates of birth may have leaked as a result of the data breach.
Typeform has said it identified the breach on 27 June, with the data having been accessed from a partial backup of 3 May.
The ARM statement said: "Some ARM supporters were among those affected by this breach. The same day we informed the affected ARM supporters, gave them advice on measures they can take to protect themselves from any consequences.
"We also announced that like many of their clients around the world we are reviewing the future use of Typeform in our campaign activities. We chose a leading provider for the form service and the breach that's occurred is not acceptable to us.
"The information released does not include any financial information, credit card details, or passwords. The ARM's own data stores are held separately and have not been compromised."
The LDP said in a statement: "Typeform have informed us that an external hacker managed to get unauthorised access to one of our recent Member Experience Survey and downloaded the results.
"This survey contained names and email address, so we are asking affected members to watch out for potential phishing scams or spam emails. This survey also contained information about political opinions, such as the campaigns and policy areas that are most important to you."
Apart from the two Australian organisations, British digital bank Monzo has also said it was affected by the breach.
