Over the last two weeks, 14 RFIs are open for work relating to fluidic, bolting and raw material for the 12 vessels, which will be built by French designer, Naval Group (formerly DCNS).
Naval Group is looking for companies specialising in steel bars, titanium bars, stainless steel forged parts, copper alloy forged parts, castings, flow regulators and valves.
In a cover letter available to businesses, Naval Group said it is crucial that Australian businesses are capable of meeting the company's "technical, time-scale and safety needs".
"The purpose of this RFI is to collect written information from Australian companies on their capability to supply products and technologies required to manufacture and sustain these submarines in Australia," the letter said.
"We have to ensure that the potential Australian suppliers are able to address our technical, time-scale and safety needs. This RFI is therefore important to provide an understanding of the capabilities of Australian industry."
Naval Group is also seeking RFIs for static converters, variable frequency inverters, air pollutant removal system, hydraulic accumulators, hydraulic power plant and gas analysers.
Submissions for RFIs close 5 January 2018. Businesses looking to submit RFIs can access the information on the ICN gateway here.
Naval Group was selected as the designer and builder of Australia's Future Submarines in 2016.
The submarines will be built in Adelaide with construction to commence in in 2021-22. Construction will run into the late 2040-2050 time frame.
