CAPE TOWN, Sept 27 (Reuters) - About 1,000 South African workers ended a strike on Thursday at a soccer stadium construction site for the 2010 World Cup, a union official said.

It was the second time in a month that workers at Cape Town's Green Point, one of 10 stadiums being built or refurbished for the 2010 tournament, had walked out.

'We have reached an agreement, so we are all happy,' Joe Brown, national co-ordinator for the Building Construction and Allied Workers' Union (BCAWU), told Reuters.

The workers downed tools last week to demand better travel benefits. Some threw stones and bricks during the illegal stoppage, injuring a police officer.

Brown said the employers had agreed to provide transport for workers to the site from nearby Cape Town train station and compensate them for past travel costs.

Organisers are under pressure to ensure that stadiums and other preparations are completed on time and have played down the prospect that the country's powerful labour unions could delay or block the effort.

South Africa has experienced a wave of industrial action this year, including a month-long civil servants' strike that brought services at schools and hospitals to a near standstill.
