Coach Ewen McKenzie has punished 15 of his players for a drinking session in the lead-up to Australia's 32-15 win over Ireland.
Pulver believes McKenzie's move was 'entirely appropriate' as he attempts to rebuild Australia's national team.
The group consumed 'inappropriate levels of alcohol' on the Tuesday night, ahead of their day off on Wednesday.
"Personally I am very disappointed that action was required," Pulver said.
"Clearly we are in a rebuilding mode in the case of Australian rugby, Ewen McKenzie is our new coach and he is laying very clear standards in terms of discipline and culture that he is looking to develop inside the team.
"So I think the actions he has taken are entirely appropriate."
Six players - Adam Ashley-Cooper, Nick Cummins, Benn Robinson, Liam Gill, Tatafu-Polota-Nau and Paddy Ryan - have been handed one-match suspensions.
All but Ryan will serve those bans against Scotland on Saturday in Edinburgh with the 25-year-old prop set to sit out against Wales instead due to rugby's international rules on the number of front-rowers required in each matchday squad.
Pulver explained why the sextet received such strong punishment, while the other nine players received written or verbal warnings.
"There were three groups in this particular instance. There were those that most significantly infringed the behavioural standards we have and they received a sanction of missing one Test match," the ARU CEO said.
"There are those that received a written warning and those that received a verbal warning.
"So clearly, any continued violation of that particular behavioural code would be an escalation of the sanction."
