In the 21st century, major Wiradjuri groups live in Condobolin, Peak Hill, Narrandera and Griffith. There are significant populations at Wagga Wagga and Leeton, New South Wales and smaller groups at West Wyalong, Parkes, Forbes, Cootamundra, Cowra and Young.

The Wiradjuri tribal area has been described as "the land of the three rivers, the Wambool later known as the Macquarie, the Kalare later known as the Lachlan and the Murrumbidgee (Murrumbidjeri). The Murray River formed the Wiradjuri's southern boundary, the change from woodland to open grassland formed their eastern boundary.
Occupation of the land by the Wiradjuri can be seen by carved trees and campsite remainders. Carved trees are more commonly found around the Macquarie and Lachlan rivers in the north rather than the Murrumbidgee in the south. Campsites, which indicate regular seasonal occupation by small groups, have been found on river flats, open land and by rivers.
Norman Tindale quotes Alfred Howitt as mentioning several of these local groups of the tribe, for example, the Narrandera (prickly lizard), Cootamundra (Kuta-mundra) from kutamun turtle, Murranbulla or Murring-bulle (maring-bula, two bark canoes). There were differences in dialect in some areas, including around Bathurst and near Albury. The Wiradjuri are identified as a coherent group as they maintained a cycle of ceremonies that moved in a ring around the whole tribal area. This cycle led to tribal coherence despite the large occupied area.
The name of the town of Wagga Wagga comes from the Wiradjuri word Wagga meaning crow, and to create the plural, the Wiradjuri repeat the word. Thus the name translates as 'the place of many crows'.

The short story "Death in the Dawntime", originally published in The Mammoth Book of Historical Detectives (Mike Ashley, editor; 1995), is a murder mystery that takes place entirely among the Wiradjuri people before the arrival of Europeans in Australia. The story prominently features various concepts in Wiradjuri folklore and tradition, such as the ngurupal: this is an area within the tribal territory which is a public assembly space for adult male Wiradjuri who have been formally initiated into manhood, yet which is forbidden ground for females or uninitiated males. Some of the dialogue in this story is in the Wiradjuri language. "Death in the Dawntime" was written by F. Gwynplaine MacIntyre, a British author who spent his formative years in the Australian outback, where he encountered representatives of many Aboriginal cultures.
In Bryce Courtenay's novel "Jessica", the plot is centred in Wiradjuri. Jessica's best friend was from Wiradjuri.
