    1 April 2026 - Shiprock
    Huge seas since last Thursday evening, so no diving anywhere till yesterday. Went in 9 mins before high but the incoming current stopped about 10 mins early and outgoing started about 15 mins early. Actually got quite strong after about 15 mins of changing. Viz 3-4 metres and warm 21.0C. Went in at pool and over wall, only went to last bommie and plaque bommie, then normal. No nudibranchs at all, a few octopus, large numbrays, one medium wobbegong shark, one moray eel. Lots of luderick and seapike, one pineapplefish. Could not look for anglerfish as my right ear would not clear near the end. A very average dive really. Visibility poor.

    2 April 2026 - Bare Island Isolated Reef 1
    Flat seas but a 15 second period meant a bit of surge even deeper. Viz varied from 2-3 m shallow and 3-4 or more on IR1. Huge seas have destroyed my rockpile at exit, rebuilt it at end. Also huge amount of sand missing from Shark Fin and Outboard Motor, fully visible, as is a large pole. Found the BBSH in normal spot but no PPH at all, Found a RIF past SHR, first one seen since December 2024. for 12 months. Lots of yellowtail on IR1 and cleaner on S side. Back looking for Whites sea horse, not found, but seen by buddy on Tuesday. Back via Cave, more yellowtail here. Saw the USDP and three sawtooth pipefish in same spot as recent dives. Back via normal way. Found another smaller RIF near LR and then found a large spotted RIF back near 44 gallon drum. Back to exit, collecting rocks for pile as I went. A fair dive. Visibility poor. 

    3 April 2026 - Inscription Point to The Monuments (and back)
    Decided to go left towards The Monuments and then back. Turned around at 55 mins or so. Viz varied between 3-4 m and 7-8 m, mostly the latter and still some surge. Cooler at 18.9C too. Found two sea dragons, although Andrew reckons he showed me a third one. A few nudibranchs, some rays and a large numbray. A shrimp in a trunicate and Mandy said she saw three red shrimps in the red weed but they disappeared when she went to show us. Only a fair dive. Visibility fair.

    4 April 2026 - The Leap (boat dive)
    Club dive day and BBQ, three boats and about 20 divers, two runs each. Very strong S wind and largish rough SE swell. First group dropped in at The Leap Deep but stronger wind now. Bluish water and viz 10-12 metres for most of the dive, a bit worse near end. Started just NE of The Leap shore entry. Not a huge amount to see, a few nudibranchs, a large school of yellowtail for a 10 mins or so mid-dive, a small yellow boxfish but that is about it. Only an average dive, but a great BBQ after. Rain basically held off all day. Visibility good.

    9 April 2026 - Osborn Shoals
    Club boat dive, two boats and nine divers. Anchored on sand and had to move S to the reef. Then went E and then S as normal. A fair bit of surge despite flat seas. Viz 8-10 metres, a bit of sand floating around. Not as much fishlife as early March. Came back to anchor and then W for a bit, could not find the boarfish but second group did. A few nudibranchs, lots of old wives, a few other fish. Only an average dive. Visibility fair.

    11 April 2026 - Bare Island Right
    Cancelled tomorrow's boat dive due to very strong W winds, 2 m 13 second swell. Was much better than the forecast although (similar to tomorrow), flat seas, viz 5-7 m and warm. Wind was strong SW though. RIF have moved all around, I saw three but some saw four. Mine were near SHR, AR, and one in between these. The two PPH were back near SHR, two sawtooth pipefish and one USDP near Cave. Some moray eels, an octopus, sole, some yellowtail out near SHC. The White's sea horse is still missing. Went looking for the pylons that were washed from the bridge on island side, could not find them. Put some more large rocks on the pile. A reasonable dive. Visibility fair.
