Sydney's west braces for flood after dams spill over

Residents to the west of Sydney are moving livestock to higher ground and bracing for flood as dams spill over following torrential downpours on Australia's eastern seaboard over the past days.

Local emergency services have attended to more than 1,700 calls for assistance and 90 flood rescues, a State Emergency Service spokeswoman told local media on Thursday.
