The Bureau of Meteorology's fortnightly climate driver update shows the current wet weather drivers are hanging on.
The La Niña is now well under way over the Pacific Ocean.
Six of the seven models assessed by the BOM indicate it will persist through December but all have it breaking down in early 2023.
But according to the update, across to the west the Indian Ocean Dipole (IOD) has started to slip.
The negative Indian Ocean Dipole is still officially in place but for the first time the IOD index values have fallen into the neutral zone since the event was declared in winter.
The systems are variable and natural so the bureau requires the neutral index values and corresponding ocean and atmosphere responses return to neutral for an extended period before declaring the event over.
But the change is a good indication that it is on the way out.
A declining IOD is entirely normal for this time of year.
The IOD pattern, whether it be positive or negative, usually breaks down as the monsoon shifts south in spring or early summer.
Even as the negative IOD decays, above-median rainfall is still expected for northern and eastern Australia over the coming months while the La Niña's influence remains.
Even normal rainfall would bring a risk of flooding on ground already sodden for much of eastern Australia.
The heavy rainfall is expected to shift north, focusing on the tropics and subtropics which traditionally get summer rain.
But with so much moisture available, south-eastern Australia is also forecast to have above average rainfall in the coming months.
Keen weather watchers will also note that the Southern Annular Mode briefly dipped into a negative phase at the end of October but it has since returned to positive, where it has been over the past few months.
Even keener watchers will note a moderate pulse of the tropical Madden-Julian Oscillation is currently sitting over the western Pacific.
The update states that this could bring rain, particularly for northern Queensland, and put a bit of a dampener on the trade winds.
On the topic of the tropics, tropical cyclone season officially kicked off on November 1.
Both the La Niña and the, albeit declining, negative IOD encourage early and increased numbers of tropical cyclones.
