The WA Health Libraries Network has a single user login to Australian Standards Online via the i2i Platform. Further information is here: Standards - Department of Health Library - Dept of Health Library at Department of Health Library. Once you have registered may gain access from the site from the link below but if the licence is in use, you will not be able to download until the previous person logs out. You can check status from the top menu item called 'Tools', then 'Current licence usage'.
Australian standards are available, however the online site also references other international standards from organisations such as
AAMI - Association for Advancement of Medical Instrumentation
ANSI - American National Standards Institute
ISO - International Organization for Standardization.
These online standards are 'locked' unless an additional purchase is made. The cost to unlock them is charged back to the part of WA Health that requires access.
When you click 'Request Unlock' you will need to fill in some details and then hit 'Submit Form'. The request will be sent to the NMHS Library to organise the purchase. Costs will be generally be charged to the department making the request. Approval is required from the head of department and the relevant business manager (and the cost centre is required) but the Library staff can organise the payment and alert you when it is available.
