Wreck dive instructor

Malta is a tiny archipelago with the densest concentration of shipwrecks in the Mediterranean: 25+ hulls within an hour of the shore. Local dive centres teach guests to dive down to them year-round, and wreck instructor here is a separate position that's constantly understaffed.
The big myth: that this is "a job for backpackers for six months between university and adult life." In Malta a wreck instructor is a normal profession with a salary above divemaster level, social security contributions, and a real career ladder all the way to owning your own centre. People live this way for decades.
Malta is a rare case where some of the ships were sunk deliberately as artificial reefs. The 110-metre tanker Um El Faroud off Wied iż-Żurrieq, the patrol boat P29, the minesweeper Rozi, the 1942 British destroyer HMS Maori – all within a single day's diving and accessible straight from the shore. There's nowhere else in Europe with a set like that.
Standard route for a foreigner:
- Open Water + Advanced + Rescue (1–2 months, around 1500 €)
- 60 dives and Divemaster (4–6 months)
- IDC and the OWSI exam (8–9 days, 3000–3500 €)
- an offer from a dive centre via DiveCareers or direct emails
- Single Permit against that offer (up to 4 months)
- relocation
The honest downside: seasonality. From December to February the water is 14–15 °C, tourists are scarce, and some centres close or cut staff – you either save through the summer or head off for the season to Egypt or Thailand. But from March onwards Malta is yours again, and those 25 sunken ships haven't gone anywhere.
