McDonald's rang up record sales of $US27 billion ($25.6 billion) in 33,510 restaurants worldwide last year, an increase of 12 per cent, turning a profit of $US5.5 billion from the 68 million customers it serves each day.

Although there is no country breakdown, it seems Australia was a weak contributor, with our stronger dollar biting into earnings and its chief executive, Jim Skinner, noting ''lagging consumer confidence as a result of the economic slowdown''.

Just 34 new stores opened in Australia last year, McDonald's US filings reveal, lifting this country's total to 865. That compared with 177 new stores opened in China.

But Australia again lived up to its track record as a hotbed of new ideas for the fast food giant. Chicken McBites have just been launched in the US after being invented here and launched in 2010. The recent launch here of smoothies and frappes have resulted in good sales volumes.

''That's something we're really proud of,'' said a spokeswoman. ''Lots of innovation in McDonald's starts in Australia, like McCafes.''

In what feel like hard economic times, McDonald's is trying to focus on value. ''The McValue lunch has been very popular,'' the spokeswoman said.

Worldwide, said the chief operating officer, Donald Thompson, breakfast at McDonald's is booming, driven partly by local offerings such as McMuffins.

''Probably the biggest of all of the menu pieces I would say is breakfast. Breakfast is beginning to circulate around the rest of the world . .. there's some tremendous opportunity there. So we've got a lot of room still in breakfast products, the premium sandwiches. Wraps are travelling. McBites are in the US from Australia and smoothies and beverages are travelling around the world. So those things are going to continue.''

In the December quarter, McDonald's reported sales of $US6.8 billion, up 10 per cent on the previous year, and net income of $US1.4 billion, up 11 per cent.

McDonald's does not give a country-by-country breakdown but the Asia-Pacific, Middle East and Africa were the strongest of its geographic regions, with sales up by 11 per cent both for the quarter, after stripping out currency impacts, compared with a year earlier, and for the 2011 full year.
