According to Wikipedia:
"The northernmost extremity of the Antarctic mainland (without nearshore islands) is Prime Head, at the northern tip of the Antarctic Peninsula at 63°12′48″S 57°18′08″W. "
Directly then, every latitude line between 63° and 90° South Latitude is covered by the Antarctic continent.
Every parallel of latitude south of roughly 60.6° S crosses some part of Antarctica, and every latitude south of about 85.5° S is entirely on that continent.
The latitude of Antarctica is approximately 66 to 90 degrees South. All lines of longitude converge at the South Pole, so all lines of longitude pass through Antarctica. Antarctica is a continent covering 10% of the earth's surface -- about as large as USA and Mexico combined. Latitude and longitude imply specific locations, not general geographies.
Antarctica. The South Pole is at 90 degrees S latitude. The North Pole is at 90 degrees N latitude. All lines of longitude converge at both poles.

No continent is crossed by every line of latitude.
The Northernmost tip of the continent is Prime Head, at the northern tip of the Trinity Peninsula at 63°12'48"S 57°18'08"W. The continent then, occupies all the lines of latitude at varying degrees to 90° S. The varying degrees are defined by an irregular coastline being measured by straight lines of latitude.
You can find Antarctica south of 60 degrees S.
The South Pole is at 90 degrees S latitude and is nowhere near Russia. The North Pole is at 90 degrees N latitude and is relatively close to Russia. All lines of longitude converge at both poles. The South Pole is located on the continent of Antarctica. There are no countries on Antarctica and no permanent population. Many countries have scientific research stations on Antarctica.
The longitude of Antarctica varies because it is a large continent. The coordinates for the South Pole, which is located in Antarctica, are approximately 0 degrees longitude, as it is where all lines of longitude converge.
Australia and Antarctica.
The only continent through which all longitude lines pass is Antarctica. This is because the lines of longitude converge at the South Pole, which is located on the continent of Antarctica. As a result, all the meridians of longitude meet at this point, making it the only continent through which they all pass.
You may be thinking of the Antarctic Circle -- 66.5628° S.
