How they differ

Louisiana also has the larger population: 4.7 million against 540,000, 8.63× as many people.
Per square kilometre that is 39 in Louisiana against 7.9 in Tasmania (Australia): Louisiana is 4.92× as densely populated.
Their centres are about 14,700 km apart.
A standard web map misstates the comparison: Louisiana at 31°N is drawn about 1.4× too large and Tasmania (Australia) at 42°S about 1.8×, so the map shows Louisiana as 1.32× the size of Tasmania (Australia) instead of 1.76×.
Together Louisiana and Tasmania (Australia) cover 188,000 km², close to the size of Syria (186,000 km², 0.9% smaller).
The gap between them, 51,400 km², is about the size of Costa Rica (51,200 km²).
At Tasmania (Australia)'s density, Louisiana would have 947,000 people (it has 4.7 million). At Louisiana's density, Tasmania (Australia) would have 2.7 million (it has 540,000).
Louisiana's centre is 73.0° of latitude, about 8,120 km, farther north than Tasmania (Australia)'s.
Louisiana is the 32nd largest of the 51 states and districts of the United States and covers 1.3% of its area; it is the 26th most densely populated of them.
Tasmania (Australia) is the 7th largest of the 8 states and territories of Australia and covers 0.9% of its area; it is the 4th most densely populated of them.
Louisiana lies about 73° of latitude (roughly 8,120 km) north of Tasmania (Australia), on the other side of the equator.
Shared out evenly, each person in Louisiana would have about 25,670 m² and each person in Tasmania (Australia) about 126,230 m².
Laid side by side, Louisiana and Tasmania (Australia) would cover 188,000 km², about the same size as Syria.
Together they have 5.2 million people, about as many people as Liberia.

Sources and method

Outlines: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
Boundary: De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
Drawing: Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
