Hello, I am looking for a possibility to send two motorcycle from south India to Australia, Perth.
Does anyone have any advice? Aircraft or ship, does't matter.

I have not done specifically that, but in January 2008, I sent my bike from Chennai to Bangkok, and a few months later from Bali Indonesia to Perth. Both transports were done by air. I did ask for seafreight as well, but at least from India to Thailand, the prices quoted were roughly the same for air and sea transport, so that made my decision very easy! And at that time, there was also talk of some sort of “slow-down strikes” at Chennai seaport, so nobody seemed to have a clue, if it would have taken 2 weeks or 2 months to send by sea!

Do note, however, that while sending from India is totally possible, it is a lot of work. I remember thinking, that I spent about 1 working week in Chennai “fully employed” just to get everything arranged. The bike was flown on an open crate, and we needed a “non-objection certificate” from the high police commissioner in Chennai. And also the freight agent could not handle all customs stuff (probably were not certified to do the Dangerous Goods certificate), so there was another customs agent, and I was shuffling between those places on an autorickshaw many many times!

But if you take it as an experience in itself, then surely it is do-able. Though I do not have personal experience, I would personally be a bit suspicious about seafreight out of India, especially how long it is gonna take in reality. And even by air, the bureaucracy over there was a bit of a handful. Good luck!

We also did air freight from chennai to bangkok earlier this year using Govias for the agent. We did spend a good week going thru the motions but no extra agent to deal with. It was pricey but it's India. All doable, just a lot of waiting.
