He said police have learned many lessons this year and are building on knowledge gained in earlier raids.
The Rebels are relatively new arrivals from Australia but have already attracted police attention on multiple occasions.
Today's operations were a sequel to Operation Stamp, which netted firearms, drugs, cash and over 30 arrests back in February.
Local Rebels' members have regular contact with their Australian colleagues, according to Bensemann.
He said prospective Rebels members should reconsider their career options.
"The message I'd pass on is if you're thinking of joining, think twice. Join them and you can expect the attention of Police.''
Bensemann said the operation would take methamphetamine off the streets and would be welcomed by drug-ravaged communities.
"What offends me about the Rebels in particular is that they're not restricted to selling drugs to adults. Those drugs make their way to our teenagers and young people.''
Rebels MC spokespeople in Australia were unavailable for comment this evening.
