Not recent. Currently in the southern Flinders, heading north.
Explore the Waukaringa ruins north of Yunta.
Lake Frome is only accessible from Balcanoona Ranger Station. Many years since we drove out, but the bull dust was something to behold at that time.
Spend a few nights at Coongie Lakes out of Innamincka.
Subject to flood damage, all the roads in Diamantina NP are/were pretty good and lead to Hunters Gorge in the centre of the park.

We did the trip from Yunta up via Lake Frome to the Strzelecki (good camp spot at Wearing Ruins on the way), and on to Innamincka last year. Road was good all the way - although of course you need to check track conditions on the eve of departure as even a drop of rain can shut you down.
I recommend turning off to Merty Merty and taking the old Strzelecki into Innamincka - a much more interesting run unless you want to see Moomba.
After Innamincka it's a good trip via Cordillo Downs (great camp spot at Caldega outstation) and then join the Birdsville developmental road, where you can head west to Birdsville or east to join the Diamantine developmental road.
We went into the Diamantina NP from just south of Bedourie, but there are various alternatives - it's all a really good trip. Enjoy :-)

Can’t help you with current road conditions over your planned route but would suggest that by May some roads would have had, either a “patrol grade”, removing bad washouts & smoothing creeks crossings, or would be subject to a more intense repair, say 2 graders working in tandem & doing a full width grade. Otherwise, just take your time & take the good with the bad.

Access to Hunters Gorge is on the western side of the Diamantina, off the Boulia access road. The Rangers Station is about 5kms to the east, on the other side of the River. There’s 4 roads that pass through the Park. One from Boulia, the road Wildmax mentioned, coming from Bedourie, through Cluny, Coorabulka & Springvale stations & meeting the Boulia road at Springvale. On eastern side of the River, the River Road comes down from Winton, past Mayne Pub ruins, & road from towards Windorah comes up through Palpararra & Davenport stations.

Worth having a look at the Mayne Pub ruins if you have time.

Thanks guys, much appreciated your effort to reply.
Looks like no one has been there since the floods have subsided.
Very interested in whether you can cross the Diamantina and its associated channels from east to west near the ranger station and Hunters Gorge, as we will be coming up from the southeast. I realize there are other access routes, but I hate backtracking!!!!
