"Since the launch of amazon.com.au in December of last year, we have been focused on growing selection and services for Australian customers," Rocco Braeuniger, country manager of Amazon Australia, said in the announcement.
"Today we are delighted to add to the over 80 million products already available on the store with the launch of Pantry Food and Drinks, bringing greater convenience to customers, underscored by everyday brilliant value and fast delivery."
The company says it is looking to cater to a growing health food trend in Australia and support local health food entrepreneurs.
It's expected that Amazon will start selling fresh food and produce to Australian customers once the company bolsters its refrigerated supply chain.
In a statement put out by Amazon, Luke Hopkins, director of the Sydney-based Protein Bread Co, welcomed the arrival of Amazon's food category.
"(We are) incredibly excited to be working with Amazon Australia for the launch of its new category, Pantry Food and Drinks," he said.
"We're passionate about a fitter, healthier, happier Australia and Amazon will be a pivotal partner in bringing this dream to life by extending our healthy high protein and low carb baking mixes to a broader, national audience."
To better compete with the looming challenge from Amazon, Woolworths and Coles have been investing in new technologies and working to boost their online stores, distribution and delivery capabilities.
Last month, Woolworths kicked off a trial of its new digital basket "scan and go" system at one of its Sydney stores. After downloading a special app to their phones, customers can simply scan items they collect and pay by tapping out at a designated pay station before they leave.
Meanwhile Coles recently announced it is allocating millions of dollars to automate distribution centres in the coming years.
