I have received info that JLT and Marsh are now one company.

Personally I'm not too impressed, as I'm not a fan of big Brokerages or those who operate in an area they're not actually based in. I'm also not happy with brokers who charge a 10% administration fee on top of their commission, or those who are chosen by Body Corporate Management companies as "preferred brokers" as they tend to also be "expensive brokers" and fees add up.

If you choose to use a broker, or have no choice but to use a broker, especially in a commercial or strata situation, check their fee structure out first.

Shop around, some brokers are now charging set fees rather than a percentage.

AND... I suggest you read the ACCC Interim Report, especially the section on brokers.
