Diveline is associated with technical training and gas support alongside recreational courses, which places it among the Victorian businesses relevant to divers progressing past recreational limits.
Victoria has one of Australia's most developed technical diving communities, and the reason is geography. Port Phillip Heads has walls beginning at around twelve metres and continuing beyond ninety. The Ships' Graveyard outside the bay contains numerous deliberately scuttled vessels across a wide depth range. That terrain gives Victorian divers a genuine reason to train past recreational limits, and it sustains the instructors, gas blending and equipment support that make the training available.
Oxygen fills are documented alongside air and Nitrox, which is a meaningful distinction. Recreational enriched air support requires a compressor, a blending system and an analyser; high-oxygen decompression gas support requires oxygen-clean cylinders, oxygen-compatible regulators and staff trained to handle them. They are different capabilities and a business offering EAN32 does not automatically offer the second.
The recreational side covers the ordinary needs of Melbourne divers: certification, continuing education, equipment and the fills that make regular diving practical.
For technical divers, the specifics matter more than the label. Establish separately: the technical agency and maximum course level; whether helium and Trimix are blended on site and how reliable supply currently is; which CCR units are supported and whether sorb is stocked; whether cylinders can be oxygen cleaned and hydrostatically tested in-house; and stage cylinder hire availability.
Helium availability in particular should be treated as time-sensitive everywhere in Australia — global supply fluctuates, and a business blending Trimix last season may not be doing so this month.
Victorian technical divers should treat helium as a trip-planning variable rather than a given. Supply fluctuates globally, prices move, and the sensible approach is to confirm availability close to the date rather than assume it from an earlier conversation.
Use the documented profile as a shortlist, then confirm the details that can change with staff, weather and season.

Local context
Prepare for Melbourne, Victoria
Regional water temperature is roughly 11–20°C through the year, with visibility Variable, commonly 3–15 m in the bay and clearer offshore. Build exposure protection and experience around the actual site, not the state-wide average.
