This site is known as a prime spot for fossilised teeth hunting — including megalodon and seal teeth — and features rocky reef terrain with ledges and gutters teeming with temperate marine life. Its relatively shallow profile makes it an excellent introductory dive site for beginners, while the chance to find ancient fossils adds a unique draw for experienced divers. The reef lies within Portland Bay, protected from the worst swell, but conditions can vary with tide and weather.","beginner",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.0042156880471880195,0.01018687890272812,0.17719067490647597,0.038991572308003826,0.13008706372617224,0.003411639033620929,0.0052598922977803,0.00444313848454731,0.008934180545435011,0.1306209552364187,0.054607988031962075,0.033684994487025555,0.010153190844770468,0.13679199280720847,0.011935873548443285,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],164.81877794608818,281.3254805989403,255.72802287811925,115.49375378058507,44.443082427305285,115.07915459182288,169.02806066981793,246.4019061295407,291.1766945383901,237.4092098304426,250.71204209281507,224.18044630931877,7.714665238233578,113.3329481198889,120.5075285582604,"EOT20","1992-01-01T00:00:00Z",[110,116,119,123,128],{"name":111,"description":112,"severity":113,"season_start":114,"season_end":115},"Variable weather and sea conditions","Portland Bay can be exposed to southerly swells and strong winds that reduce visibility and create challenging conditions.","caution",5,10,{"name":117,"description":118,"severity":113,"season_start":56,"season_end":56},"Limited visibility","Like many temperate Victorian dive sites, visibility can vary significantly depending on recent weather and plankton blooms.",{"name":120,"description":121,"severity":113,"season_start":114,"season_end":122},"Cold water temperatures","Victorian waters remain cold year-round; exposure and hypothermia risks require appropriate wetsuit thickness.",11,{"name":124,"description":125,"severity":126,"season_start":36,"season_end":127},"Boat traffic","The area is frequented by boats; snorkellers should display a dive flag and remain vigilant at all times.","warning",12,{"name":129,"description":130,"severity":113,"season_start":131,"season_end":132},"Swell conditions","Best dived in low swell with light north or northerly winds; exposed to rougher conditions when winds shift.",6,9,{"directions":134,"parking":135,"facilities":136,"fees":139,"access_method":140},"Minerva Reef is located in Portland Bay, approximately 5 km north-northeast of Portland, Victoria.
