Welcome to the September 2023 Jetty Dive Debrief! This is our newest addition to the blog – the “debrief”. Here we are going to let you know how the water has been, what the season showed us, any interesting or noteworthy details, and what we’ve achieved as a shop!

Seasonal Marine Life Activity:

We had not too many dives out throughout August, but had the usual characters like Grey Nurse Sharks, Black Cod, and Turtles.

On the 3rd of September we had 12 Grey Nurse Sharks, 12 or more on 24th, 20 on the 25th, and 20 (give or take a few!) on the 27th.

We also spotted some QLD Gropers on the 3rd, 10th, and 24th of September. There were two cuttlefish on the 10th, and one on the 16th and 24th of the month. There were also two octopus on the 16th, and the 24th.

We saw a variety of turtles throughout the month, with Green Sea and Hawksbill on the 16th, a Hawksbill and 4-5 green sea turtles on the 24th. There were 6 turtles on the 25th, one on 27th, and loggerhead on 27th. We also saw a yellow boxfish on the 16th!

Exitingly, we had some hammerhead shark sightings! On our whale watching trip on the 27th we saw a little baby hammerhead swimming just outisde the harbour around the boat! And on the following day we saw 8-10 in a school swimming, and then two on the second dive on the 28th.

Whale Encounters

We are still running our whale trips until mid-way through October, with lots of amazing encounters! Plus, on the 27th, our diver boat encountered a little calf on the way back to shore after their dive. This calf mugged the boat for a little while! What a treat.

The first dives of the month had great visibility, but it fluctuated throughout the rest of the month. Take a look at our graph below for a more detailed and visual look at the visibility.


The temperature was quite steady, with a few warmer spurts! Check out our charting of the temperatures below.

Sustainability and the environment

This section we are dedicating to showing what steps we are taking to reduce our environmental impact. It might include incentives we have implemented or tried through the month, or programs we have participated in. We intend to expand upon our conservation efforts page with everything we have implemented in store – as we are doing much more than this page shows!

Sent away another box of Single-Use Coffee Cups! I sent away 55 cups and lids, and some other bits and pieces! I added in my used toothpaste tubes and moisturiser tubes from home, empty blister-packs from the Kwells the team have used in store, and empty/used pens, highlighters, and empty white-out-tapes we’ve used in office.

Happy Whale!

Whenever we are able, we send in our Whale Tail (Fluke) images to Happy Whale to record our sightings! Each Humpack Whale has a completely individual tail, so Happy Whale identifies and tracks the whale’s movements!
You can see our uploaded whales here.

If you’d like us to submit a whale tail image on your behalf, just send it through to us in email and I will do it for you! Otherwise head to Happy Whale to upload your own.

The Month Ahead!

October is heading towards the brief time of year that we get a bit of a break! The whale season is wrapping up and we are getting our footing again in time for a (hopefully!) busy Christmas Holiday period.

Hammerhead season is always an exciting time in the water, so get in with some dive bookings to see if you can be a lucky one who spots one in the water!
