It is possible. Conditions were there today, now it just needs luck from someone.
I had 10m QSO with VK6 this morning on 10w. I could also hear @VK3JBL calling on 10m with a decent copy on summit Vk3/VT-013, but I stupidly had put up the 20m vertical and couldn’t respond. By the time I put up the 10m vertical it was too late.
Noooo! I didn’t spend a lot of time on 10 as the band seemed a bit dead. Generally was not good all day on Sunday, except to ZL though grabbed the odd US and JA contact.
Sorry was a bit quick on the last summits of the day (5 in total, 6 if you include the campsite). The sun had set by the time I arrived at the last (VT-022) and fog/cloud had blanketed the range. I had a long drive out in fog so thick I couldn’t see the side of the road or the road at all at points and that’s a mind numbingly long drive out in good condx. I arrived home at 10pm.
Sunrise on VK3/VE-033:

Time to refresh this topic, as equinox on 23rd September and the VK time change on 6th October coming nearer.
My alert is up for 12th October 0630 z 28 Mhz. Wx depending.

I’m not sure how I missed this topic previously… I must have had blinkers on earlier in the year.
In the past I’ve enjoyed participating in several EU <> VK/ZL/JA S2S events with some success, all having been good fun ascending to the summit in the dark and setting up as dawn breaks. I hope something comes of this over the coming months. 
Most of the stations taking part in the challenge in March/April seemed to be equipted for 20 m, too. So they could joyfully grab the VK/EU LP s2s even when 10 m was dead.

Decent F2 condx on 10 m today. 2 VKs in the log. No s2s, however.
Propagation to VK seemed a bit patchy. Here are the UTC times.
0718 VK4DO not completed, qsb
0747 VK2CR 59 / 57
0820 VK3OCD 55 / 44
I agree and am going to have to dust off the alarm clock for a weekend soon to try a VK/ZL S2S on 10m. conditions are getting there!
VK6s 53 SSB or so around 1200Z on 10m on Sunday.
Thanks, useful ! I heard you working VE3 on the key on Sunday ! Conditions were great. Well I heard the VE station and not you/MM, otherwise I would have worked you! It was rather hopeful
