Melbourne has a temperate oceanic climate (Koppen climate classification Cfb) and is well known for its changeable weather conditions. This is mainly due to Melbourne's location situated on the boundary of the very hot inland areas and the cool southern ocean. This temperature differential is most pronounced in the spring and summer months and can cause very strong cold fronts to form. These cold fronts can be responsible for all sorts of severe weather from gales to severe thunderstorms and hail, large temperature drops, and heavy rain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Is Melbourne known for changeable or steady weather patterns?
Ah, so.. changeable

The region's economy greatly depends on agriculture; rice and rubber have long been prominent exports. Manufacturing and services are becoming more important. An emerging market, Indonesia is the largest economy in this region. Newly industrialised countries include Indonesia, Malaysia, Thailand, and the Philippines, while Singapore and Brunei are affluent developed economies. The rest of Southeast Asia is still heavily dependent on agriculture, but Vietnam is notably making steady progress in developing its industrial sectors. The region notably manufactures textiles, electronic high-tech goods such as microprocessors and heavy industrial products such as automobiles. Oil reserves in Southeast Asia are plentiful.

Voyager 2 is the only spacecraft that has visited Neptune. The spacecraft's closest approach to the planet occurred on 25 August 1989. Because this was the last major planet the spacecraft could visit, it was decided to make a close flyby of the moon Triton, regardless of the consequences to the trajectory, similarly to what was done for Voyager 1's encounter with Saturn and its moon Titan. The images relayed back to Earth from Voyager 2 became the basis of a 1989 PBS all-night program, Neptune All Night.
