Zac Swindells ispONE director said the deal will provide customers with a choice of internet and data products.
"We are very pleased to have partnered with Optus Wholesale to provide our clients with superior mobile broadband products and services," said Swindells.
"Innovation and development of information communication technology (ICT) means that mobile broadband is rapidly becoming a cost-effective and user-friendly alternative to fixed line broadband.
"It has been widely acknowledged that mobile broadband sales will surge in 2009 and will surpass that of fixed line broadband in the next three to four years," he added.
Vicki Brady managing director, Optus Wholesale said given the nature of ispONE's client base, the agreement will enhance its efforts to support ISPs to service regional and rural Australia.
ispONE said the deal will allow it to provide a stronger product suite to new and existing customers.
"As an example, one of our existing clients, energy provider Country Energy, has been using the Optus 3G network to provide its users with mobile broadband services," said Swindells.
"We anticipate that many similar companies and existing ISPs will diversify their product offering to capture market share in the booming mobile broadband sector," he added.
