TL;DR: Serological tests of children and domestic fowls gave supporting evidence of the occurrence of infections with Group B arboviruses, and also demonstrated infections with Sindbis and Ross River virus.

TL;DR: HI responses were found to low titre to Koongol and Wongal viruses in sera from cattle, wallabies, wild birds, bandicoots and domestic fowls, but could rarely be confirmed by neutralization test and are considered of uncertain significance.

TL;DR: Serological tests on bird serum or blood gave additional evidence of infection with Group B arboviruses, Sindbis, Corriparta and Koongolg Group viruses.

TL;DR: The results are considered not to support (but do not exclude) the possibility that the viruses of the Murray Valley encephalitis virus subgroup of Group B, active in northwest Queensland in the wet season but not yet detected there in the dry season, may survive throughout the year in rain forest near the east coast of North Queensland.

TL;DR: The results are discussed as showing the need to seek for evidence that Kunjin and Sindbis viruses may cause disease in western Queensland and as indicating problems in serological diagnosis of epidemic polyarthritis in communities with high prevalence of antibody to Ross River virus.
