Quite aside from it being a cyclone or not, I find it fascinating that a weather system like this has a "life" as such, identifiable over long periods of time and travels.

The official outlook is

Tropical Cyclone Outlook for The Coral Sea

IDQ10810
Tropical Cyclone Outlook for Coral Sea

Issued at 2:30 pm EST on Wednesday 11 April 2018
for the period until midnight EST Saturday 14 April 2018.
Existing Cyclones in the Eastern Region:

Nil.
Potential Cyclones:

At 1pm AEST Wednesday, ex-tropical cyclone Iris was situated in the northern Coral Sea. The system is expected to move slowly westwards on Thursday and remain offshore from the Queensland coast during the outlook period.

There are no other significant systems in the Coral Sea and none are expected to develop during the next three days.

Likelihood of a tropical cyclone in the Eastern Region on:
Thursday:Low
Friday:Low
Saturday:Low

You're not wrong and life does appear to be breathing back into her (if I have it right), plenty of convection on satview but TPW animation shows a lot of dry air to her south and comin up fast.
Hang in there baby

B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (REMNANTS OF 17P) PREVIOUSLY
LOCATED NEAR 14.5S 154.2E, IS NOW LOCATED NEAR 12.5S 151.8E,
APPROXIMATELY 436 NM NORTHEAST OF CAIRNS, AUSTRALIA. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS CONSOLIDATING BANDING
WRAPPING INTO A WELL-DEFINED LOW LEVEL CIRCULATION CENTER. A PARTIAL
102341Z METOP-A 89GHZ MICROWAVE IMAGE SHOWS WELL ORGANIZED LOW LEVEL
STRUCTURE AND DEEP CONVECTION. RMNTS 17P IS EXPERIENCING LOW
VERTICAL WIND SHEAR (5-10 KT), AND STRONG DIVERGENCE ALOFT AND BOTH
POLEWARD AND EQUATORWARD OUTFLOW ARE FUELING CONVECTION. SEA SURFACE
TEMPERATURES ARE WARM (28-29C) AND ARE CONDUCIVE TO DEVELOPMENT.
SOME GLOBAL MODELS PREDICT RMNTS 17P TURNING SOUTHWESTWARD AND
REDEVELOPING INTO A TROPICAL CYCLONE IN THE NEXT SEVERAL DAYS,
THOUGH NOT ALL MAINTAIN THE CIRCULATION. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
(2) NO OTHER SUSPECT AREAS.//
NNNN

Total Precipitable Water is not looking good for Iris as the dry air pushes north over the coral sea, however she looks brilliant on the satellite so maybe the warm SSTs will push that dry air away.

that’s amazing, thanks for the link I’ve bookmarked that one.

BOM still only going for a low chance of development in the next 3 days.

thats all she wrote..

Tropical Cyclone Outlook for Coral Sea
Issued at 2:30 pm EST on Friday 13 April 2018
for the period until midnight EST Monday 16 April 2018.

Existing Cyclones in the Eastern Region:
Nil.

Potential Cyclones:

The surface circulation of ex-tropical cyclone Iris has continued to weaken in the far northern Coral Sea near Papua New Guinea. It is now rated a very low chance of redeveloping into a tropical cyclone.

There are no other significant systems in the Coral Sea and none are expected to develop during the next three days.


Likelihood of a tropical cyclone in the Eastern Region on:
Saturday:Very low
Sunday:Very low
Monday:Very low

Say it isn't so...!!!!

There's still some rotation/convection going on...don't write the ol' girl off just yet...

Barely hanging in there.
Would love to see her go travelling again.

That's all she wrote folks. Iris had a good innings.

Good riddance I say. It did nothing but continue the extended dry spell we are going through. Not a drop of rain from it.

Certainly cant complain here, we got some rain from Iris

When you say "we" you mean Rockhampton?

Has she actually finally......gone?

Hard to believe isn't it. One of the most impressive systems ever(if somewhat underwhelming). What a stayer.

Here's the path Iris/ex-Iris took during its life up to 00z Friday:

Thank you Ken. Appreciate the track.

I reckon you can still just see her (well the remains) just north of Cape Melville
