Looks like winds are the reason why they keep pushing the date.

Rocket's turn.
TestFlight1 Update 🚀
✅ ICYMI, payload fairing is on
☑️ Fixes are in — testing continues
✅ Regulatory notifications have been issued
We were aiming for a June launch, but the weather isn’t cooperating. We’re now targeting a narrow launch opportunity 𝗡𝗼 𝗘𝗮𝗿𝗹𝗶𝗲𝗿 𝗧𝗵𝗮𝗻 (𝗡𝗘𝗧) 𝗝𝘂𝗹𝘆 𝟭.
NOTE: this date remains 𝗵𝗶𝗴𝗵𝗹𝘆 𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝘁 𝗼𝗻 𝘄𝗲𝗮𝘁𝗵𝗲𝗿, 𝘄𝗶𝗻𝗱𝘀, 𝗮𝗻𝗱 𝗼𝗻𝗴𝗼𝗶𝗻𝗴 𝘁𝗲𝘀𝘁𝗶𝗻𝗴. Please follow our socials and our Missions page (gspace.com/missions) for the latest.
PS: 𝗪𝗵𝘆 𝗱𝗼 𝘄𝗲 𝘀𝗮𝘆, “𝗡𝗼 𝗘𝗮𝗿𝗹𝗶𝗲𝗿 𝗧𝗵𝗮𝗻”?
NET is the global standard for sharing a provisional launch date — the earliest a launch could occur within an approved window.
That's because rocket launches are complex, and delays are normal. Weather, range availability, regulatory clearances, final checks (and last-minute anomalies!) can all shift timelines.
This is especially true for a first-of-its-kind test flight, where every major system is being flown for the first time.
NET dates give us the flexibility to launch when ready — and in Australia, that involves close coordination with the Australian Space Agency, CASA, Airservices, Maritime and more.

It's a new notice, and it has the same target launch date shared elsewhere.

"012130Z TO 012330Z JUL" from the notice equals July 1st (the "01") from 21:30 to 23:30 UTC ("Z" = Zulu/UTC). In Australian time zones, this window falls on July 2nd.

Oh sorry my mistake lol.

As we move closer to a potential launch date, if you guys want a high quality live stream to watch updates, chat, and more, come hang out on my stream if anyone is interested.

In the immortal words of a golden droid.
Here we go again

I hope they delay it by another day please Gilmour Space

It feels like Gilmour doesn't want to fly the rocket at this point. These delays are insane.

Spaceflight isn't just about beginner's luck. Since many others have faced failures on their first ventures, I understand the nervousness that comes with making sure everything is just right before moving forward. However, I have to admit, the delays are starting to make me feel a bit nervous too.

You're certainly right about that. However, Gilmour themselves said that they didn't expect this flight to succeed, and the vehicle is more than a year old and certainly out of date.

There is no end to the number of stories where some foreigner has mistaken Marmite for Nutella.  It's very entertaining.  (I'm NZ, Marmite is effectively the same as Vegemite but with red coloured branding.)

Anyway, I'm looking forward to hopefully the first successful hybrid rocket to reach orbit tomorrow!
